INTRODUCTION
1.1 GENERAL DESCRIPTION
IStran Communication Interfaces allow one or more intrinsically safe TeleFlow ® devices to communicate with a device located in a Division 2 or nonhazardous area.
IStran PCB assemblies have been designed to provide the following key features:
• Replaces six intrinsic safety barriers for RS-232 signals (3 in, 3 out)
• Replaces six intrinsic safety barriers for TeleFlow I/O signals (3 in, 3 out)
• Can provide 500V isolation between two devices
• Allows up to four devices to share a single radio or modem
• Operates at speeds up to 19,200bps
• The TeleFlow can receive power from outside the Division 1 area
• The TeleFlow can control power to a radio or modem located outside the Division 1 area
• IStran has been approved for use with TeleFlow EGMs (3530-10B) and TeleFlow
Correctors (3530-50B) (when equipped with approved intrinsically safe Battery/-
Solar Panel Power or when externally powered through the IStran). IStran has been approved for use with TeleFlow ECRs (3530-40B) when externally powered through the IStran).
Some of these features also make the IStran useful in applications where intrinsic safety is not required, such as providing isolation between two devices or allowing multiple devices to share a single radio or modem.

1.2 PHYSICAL DESCRIPTION
The IStran assembly measures 6.25” in length by 4.50” in width by approximately 1” in depth while the IStran Plus assembly measures 6.25” in length by 4.50” in width by approximately 1.825” in depth (see Figures 1-2 & 1-3).
The IStran/IStran Plus assembly consists of the following major components:
• One IStran PCB for the IStran assembly; Two IStran PCBs for the IStran Plus
• Yellow Alodined Aluminum Base Plate (0.060” in thickness)
• Black Anodized Cover (Top) (0.090” in thickness)
1.2.1 The IStran PCB (see Figure 1-4)
IStran PCBs provide two interfaces which are designated hazardous and non-hazardous.
Eack interface can be configured independently to operate in switched or unswitched mode.
Switched mode can set the TX drivers into a high-impedance state to reduce power consumption. In cases where power consumption is not a key factor, the interfaces should be configured for unswitched mode. In unswitched mode, the TX drivers are always active and they always follow the corresponding RX inputs.

If no Jumper is installed, or if a Jumper is installed between pins 1 and 2 (SW), the hazardous interface operates in switched mode. If a Jumper is installed between pins 2 and
3 (UNSW), the hazardous interface operates in unswitched mode.
2.2 SWITCHED & UNSWITCHED MODES
Each IStran interface can be configured independently to operate in switched or unswitched mode. In switched mode, the TX drivers can enter a high-impedance state to reduce power consumption. The outputs transition smoothly, without glitches, to and from the high-impedance state. Most modern device inputs will pull the high impedance IStran output to ground and interpret it as a low, or MARK state. Some devices may not properly interpret the high-impedance signal, and in some systems it may be impractical to operate either or both interfaces in switched mode. In these cases, or when power consumption is not a concern, the interface(s) should be configured for unswitched mode. In unswitched
Instruction Manual Page 6 CI-3530-IStran (01/05/2006)
mode, the TX drivers are always active and they always follow the corresponding RX inputs.
Switched mode is enabled or disabled for the nonhazardous interface by jumper position
NJP1, and for the hazardous interface by jumper position HJP1. When either interface is in switched mode, it is turned on or off by the RX3 (NRX3 or HRX3) input of the opposite interface.
To configure the nonhazardous interface for switched mode, place a shorting jumper in the
NJP1 position marked SW (short NJP1 pins 1 and 2). The nonhazardous interface is also in switched mode by default if no jumper is installed at NJP1. When the nonhazardous interface is configured for switched mode, the NTX outputs are in a high-impedance state when HRX3 is low (or negative), and the NTX outputs follow the HRX inputs normally when HRX3 is high (positive). To configure the nonhazardous interface for unswitched mode, place a shorting jumper in the position marked UNSW (short NJP1 pins 2 and 3). In unswitched mode, the NTX outputs are always turned on and they always follow the corresponding HRX inputs.
To configure the hazardous interface for switched mode, place a shorting jumper in the
HJP1 position marked SW (short HJP1 pins 1 and 2). The hazardous interface is also in switched mode by default if no jumper is installed at HJP1. When the hazardous interface is configured for switched mode, the HTX outputs are in a high-impedance state when
NRX3 is low (or negative), and the HTX outputs follow the NRX inputs normally when
NRX3 is high (positive). To configure the hazardous interface for unswitched mode, place a shorting jumper in the HJP1 position marked UNSW (short HJP1 pins 2 and 3) In unswitched mode, the HTX outputs are always turned on and they always follow the corresponding NRX inputs.
2.3 NONHAZARDOUS POWER OUTPUT
The nonhazardous power supply is routed through a FET (field effect transistor) from the power input to an output terminal. The power supply comes in on the NPIN terminal and switched power goes out on the NPOUT terminal. When hazardous interface signal input
HRX3 is at a high (positive) level, NPOUT is turned on and can supply power to an external device. When HRX3 is at a low (or negative) level, NPOUT is turned off. The voltage drop between NPIN and NPOUT can be determined by multiplying the NPOUT load current by the NPIN to NPOUT on-resistance. The resistance of the associated field wiring must also be taken into account when determining the total drop between the power supply and the load.
CAUTION
In order to minimize resistance between NPIN and NPOUT, no overcurrent protection is provided by the IStran. The user should install a fuse or other means of overcurrent protection at the power source to prevent damage to the IStran, power source, or load in case of a short circuit or other overcurrent condition.
CI-3530-IStran (01/05/2006) Page 7 Instruction Manual
Section 3
SYSTEM WIRING
3.1 INTRODUCTION TO SYSTEM WIRING
An IStran/IStran Plus unit connects a radio, modem, or other communications device to a
TeleFlow Model 3530-10B, 3530-40B or 3530-50B (flow computer). An IStran/IStran Plus unit can also provide an intrinsically safe interface between an external power supply,
Discrete I/O, Pulse Input, Analog Input and RS-232 signals associated with a radio, modem or TeleFlow (in a non-hazardous area) and a TeleFlow (in a Class I, Division 1 area).
3.2 GROUNDING
The IStran/IStran Plus can provide up to 500V of isolation between the hazardous and nonhazardous interfaces. When using the ground isolation capability of the IStran, devices on either side must have separate power sources, and each source must power the corresponding IStran interface. Refer to the field wiring diagrams in Section 3.4 for systems with independent power sources.
When isolation is not required, a single power source can also supply both IStran interfaces and, optionally, both connected devices. To power both IStran interfaces using a single power source, the power source must be connected between NPIN and NGND. Connector
HJ2 is then used as a jumper position to wire HPOUT to HPIN and HGND to CGND. Note that CGND and NGND are internally connected, and that CGND is connected to the IStran case. Refer to the field wiring diagrams in section 3.4 for systems with a single power source.
When a ground connection already exists between the power source and the TeleFlow or communications device, do not wire the ground terminal on the IStran communications connector (NJ1 or HJ1). The ground reference established on the IStran power connector
(NJ2 or HJ2) serves as both power supply return and signal ground reference. Wiring the communications connector ground terminal may introduce a ground loop and degrade the performance of the IStran under these circumstances. The wiring diagrams in Section 3.4 illustrate the recommended practices.
For intrinsic safety applications, redundant earth grounds are required.
Both grounds should measure less than one ohm to earth. The NGND terminal provides one ground, and the case provides the other. If the mounting panel does not provide a suitable ground path, connect a
12AWG or larger ground conductor to one of the IStran mounting screws.
3.3 CABLE LENGTH
The IStran is UL listed for use with cable lengths up to 25 feet on either or both interfaces.
Typically, the IStran is located in close proximity to the communications device (connected to the nonhazardous interface) and at some distance from the TeleFlow (connected to the hazardous interface). Because of cable capacitance and inductance, 25 feet is the maximum cable length allowable for use with a TeleFlow located in a Division 1 area.
Instruction Manual Page 8 CI-3530-IStran (01/05/2006)
Although the system is NOT TO BE OPERATED with cables that exceed 25 feet in length
(when a TeleFlow is located in a Division 1 area), the IStran will typically operate reliably with cables longer than 25 feet. The maximum reliable cable length is dependent on the type and grade of cable, the electrical interface of the device at the other end of the cable, ambient noise, and the performance characteristics of the UARTs (universal asynchronous receiver/transmitters) on both the Comm. device and the TeleFlow. Experimentation under favorable circumstances has yielded reliable operation of the IStran at 19,200 bps with up to 500 feet of cable.
WARNING
The cable length is NOT TO EXCEED 25 feet when the IStran is connected to a TeleFlow that is operating in a Division 1 area.
3.4 FIELD WIRING DIAGRAMS
Figure 3-1 below illustrates a typical radio or modem system. In this example, the modem and TeleFlow have independent power systems and their grounds are isolated from one another. Each interface of the IStran draws power from its associated supply. The power source to the nonhazardous interface must not use or generate more than 250V. If the
IStran is located in a Division 2 area, the power input and output connections must be made using Division 2 wiring methods as described in Section 4.1.
Figure 3-1 - Modem System with Independent Power Supply
Figure 3-2 is similar Figure 3-1, but in this example a single power source supplies both the modem and the TeleFlow. Note that the power supply input range for this con-figuration is
8 to 16V, and that the grounds of both devices are connected together through the IStran.
The TeleFlow or RTU power supply current must be 120mA or less, and it must operate down to 5.9V.
Figure 3-3 is similar to Figure 3-1, but shows connections to an MDS 2310 or similar radio.
In this example, radio power is switched on and off by the TeleFlow’s DTR signal (which works in conjunction with the TeleFlow’s Auxiliary Power Output). Radio communications parameters are setup in the application software resident on a PC (see Appendix F - Section F.8.5 of CI-3530-10B or CI-3530-50B). Figure 3-4 is similar to Figure 3-3, but with a single power source.

Figures 3-5 through 3-7 illustrate multidrop systems, connecting four TeleFlows to a single radio or modem. In the multidrop configuration, the TeleFlows cannot control radio/modem power. Note that one power source supplies power to the radio/modem and both interfaces of its associated IStran, as well as to the network (hazardous) interface of all of the other
IStrans. Each TeleFlow must have its own power source, and the radio/modem and
TeleFlow grounds are all isolated from each other. In this configuration, any or all of the
TeleFlows can be located in Division 1 areas, while the radio/modem and all of the IStrans are located in the nonhazardous or Division 2 area.

Figure 3-8 illustrates an externally powered TeleFlow (without a modem or radio). In this example, the external power source to the nonhazardous interface must not generate more than 16Vdc and must be able to supply at least 8Vdc. If the IStran is located in a Division 2 area, the power input and output connections must be made using Division 2 wiring methods as described in Section 4.1. Note: If a modem or radio is required, refer to
Figures 3-2 or 3-4. The only difference is that the 12V battery may be replaced by an external 8 to 16 Vdc power supply.

In this example, the external power source to the nonhazardous interface, all I/O and communications equipment must reside in a nonhazardous area. If the IStran is located in a Division 2 area, the power input and output connections must be made using Division 2 wiring methods as described in Section 4.1.

INSTALLATION
4.1 INSTALLATION INTRODUCTION
The IStran/IStran Plus and the communications device are located in a nonhazardous or
Division 2 rated area, while the TeleFlow can reside in a Division 1, 2, or nonhazardous area.
A suitable enclosure must be provided for the IStran/IStran Plus. When the IStran/IStran
Plus is mounted in a Division 2 area, the nonhazardous interface connections shall be made in accordance with Article 501-4(b) of the National Electrical Code NFPA 70.
CAUTION
When connecting the IStran to a TeleFlow mounted in a
Division 1 area, wire all circuits using wiring methods specified in article 504 of the National Electrical Code NFPA 70. Contact your IStran supplier for assistance.
WARNING
When the IStran is installed in a Division 2 area, ensure that the area is nonhazardous before connecting or disconnecting the nonhazardous interface.
4.2 INSTALLATION NOTES
Use four #6 screws with lockwashers to secure the IStran/IStran Plus to a grounded metal panel. Figures 1-2 and 1-3 show the physical dimensions of the IStran/IStran Plus units.
The four mounting holes/slots are 0.156" in diameter. Total height is approximately 1". The case material is 5052 aluminum with a black anodize finish. The thickness of the base is
0.060", and the top is 0.090". The case hardware is stainless steel.
The IStran/IStran Plus accepts stranded wires up to 14AWG. When two wires must be inserted in a single position, 18AWG is the maximum recommended size. The recommended strip length is 1/4 inch, and the insulation should not extend into the connector clamp.
Cables should use 26AWG or larger conductors and should not be configured as twisted pairs. If a shield is used, it should be connected only at one end, closest to the system ground reference. For optimum performance over long distances, use low-capacitance cables. In the multidrop configuration, all IStran units should be in close proximity.
All wiring should be secured before power is applied to the IStran or to the associated devices. For intrinsic safety applications, use a single cable to connect the IStran hazardous interface to the intrinsically safe device. Maintain a minimum 2” separation between the intrinsically safe wiring and all other wiring. The IStran hazardous interface should be physically located near the point where the intrinsically safe wiring exits the enclosure housing the IStran. No other wiring should pass through the same hole or share a cable or conduit with the intrinsically safe wiring. Secure the intrinsically safe wiring and limit
CI-3530-IStran (01/05/2006) Page 17 Instruction Manual
slack to ensure that, should one of the intrinsically safe wires become dislodged from an
IStran terminal, it must still maintain a 2” separation with either the IStran nonhazardous interface wiring or any other circuits except those on the IStran hazardous interface.
Refer to Figures 3-1 through 3-7 when connecting wires between an optional modem or radio and an IStran Assembly. Note: MDS and FreeWave radios utilize different
RXD/TXD naming conventions, i.e., MDS utilizes RXD and TXD to mean receive input and transmit output respectively, while FreeWave utilizes RXD for transmit output and TXD for receive input (see Figures 3-5 and 3-6).
Refer to Figure 3-8 when connecting wires between an externally powered TeleFlow CPU
Board and an IStran Assembly.
Refer to Figures 3-9A & 3-9B when connecting wires between an IStran Assembly and an
Intrinsically Safe Teleflow that is connected to an Intrinsically Safe Model 2808-IXX
Transmitter.
Note: Intrinsically Safe Model 2808 Transmitters are equipped with a Data Plate that states the model number as 2808-I-XX… If the ‘I’ isn’t present in the Model
Number, or if the Data Plate doesn’t explicitly state that the unit is intrinsically safe for Class 1, Div. 1 Groups C & D operation, the unit is not Intrinsically Safe and MUST NOT be used in a Class I Division 1 area.
Refer to Figure 3-10 when connecting wires associated with a Discrete Input, a Discrete
Output and a Pulse Input circuit (in a nonhazardous area) to an Intrinsically Safe Teleflow
(in a hazardous area) via one IStran Assembly while connecting wires associated with an
RS-232 device (situated in a nonhazardous area) to the same TeleFlow unit via a second
IStran Assembly.
Refer to PIP-EXP232TF when connecting wires to an IStran Assembly and an optional
Expansion Communications Port RS-232 Board.

Anti-Static Field kit. It is recommended that an anti-static field kit be kept on any site where solid-state printed circuit boards and other ESD-sensitive components are handled. These kits are designed to remove any existing static charge and to prevent the build-up of a static charge that could damage a PC board or
ESD-sensitive components. The typical anti-static field kit consists of the following components:
1. A work surface (10mm conductive plastic sheet with a female snap fastener in one corner for ground cord attachment).
2. A 15-foot long ground cord for grounding the work surface.
3. Wrist strap (available in two sizes, large and small, for proper fit and comfort) with a female snap fastener for ground cord attachment.
4. A coiled ground cord with a practical extension length of 10 feet for attachment to the wrist strap.

ESD-SENSITIVE COMPONENT HANDLING PROCEDURE
Introduction
Microelectronic devices such as PC boards, chips and other components are electrostatic-sensitive. Electrostatic discharge (ESD) of as few as 110 volts can damage or disrupt the functioning of such devices. Imagine the damage possible from the 35,000 volts (or more) that you can generate on a dry winter day by simply walking across a carpet. In fact, you can generate as much as 6,000 volts just working at a bench.
There are two kinds of damage that can be caused by the static charge. The more severe kind results in complete failure of the PC board or component. This kind of damage is relatively simple, although often expensive, to remedy by replacing the affected item(s). The second kind of damage results in a degradation or weakening which does not result in an outright failure of the component. This kind of damage is difficult to detect and often results in faulty performance, intermittent failures, and service calls.
Minimize the risk of ESD-sensitive component damage by preventing static build-up and by promptly removing any existing charge. Grounding is effective, if the carrier of the static charge is conductive such as a human body. To protect components from
nonconductive carriers of static charges such as plastic boxes, place the component in static-shielding bags.
This manual contains general rules to be followed while handling ESD-sensitive components. Use of the anti-static field kit to properly ground the human body as well as the work surface is also discussed.

General Rules
(1) ESD-sensitive components shall only be removed from their static-shielding bags by a person who is properly grounded.
(2) When taken out of their static-shielding bags, ESD-sensitive components shall
never be placed over, or on, a surface which has not been properly grounded.
(3) ESD-sensitive components shall be handled in such a way that the body does not come in contact with the conductor paths and board components. Handle
ESD-sensitive components in such a way that they will not suffer damage from physical abuse or from electric shock.
(4) EPROMS/PROMS shall be kept in anti-static tubes until they are ready to use and shall be removed only by a person who is properly grounded.
(5) When inserting and removing EPROMS/PROMS from PC boards, use a chip removal tool similar to the one shown in the figure following. Remember, all work should be performed on a properly grounded surface by a properly-grounded person.

Typical Chip Removal Tool
(6) It is important to note when inserting EPROMS/PROMS, that the index notch on the PROM must be matched with the index notch on the socket. Before pushing the chip into the socket, make sure all the pins are aligned with the respective socket-holes. Take special care not to crush any of the pins as this could destroy the chip.
(7) Power the system down before removing or inserting comb connectors/plugs or removing and reinstalling PC boards or ESD-sensitive components from card files or mounting hardware. Follow the power-down procedure applicable to the system being serviced.
(8) Handle all defective boards or components with the same care as new components. This helps eliminate damage caused by mishandling. Do not strip used PC boards for parts. Ship defective boards promptly to Bristol Babcock in a staticshielding bag placed inside static-shielding foam and a box to avoid damage during shipment.
ESDS Manual
S14006
4/15/92
CAUTION
Don't place ESD-sensitive components and paperwork in the same bag.
The static caused by sliding the paper into the bag could develop a charge and damage the component(s).
(9) Include a note, which describes the malfunction, in a separate bag along with each component being shipped. The repair facility will service the component and promptly return it to the field.
3.
Protecting ESD-Sensitive Components
(1) As stated previously, it is recommended that an electrically-conductive anti-static field kit be kept on any site where ESD-sensitive components are handled. A recommended ESD-protective workplace arrangement is shown on page 7. The anti-static safety kit serves to protect the equipment as well as the worker. As a safety feature, a resistor (usually of the one-megohm, 1/2-watt, current-limiting type) has been installed in the molded caps of the wrist strap cord and the ground cord. This resistor limits current should a worker accidently come in contact with a power source. Do not remove the molded caps from grounded cords. If a cord is damaged, replace it immediately.
(2) Be sure to position the work surface so that it does not touch grounded conductive objects. The protective resistor is there to limit the current which can flow through the strap. When the work surface touches a grounded conductive object, a short is created which draws the current flow and defeats the purpose of the current-limiting resistor.
(3) Check resistivity of wrist strap periodically using a commercially-available system tester similar to the one shown in the figure below:
5
ESDS Manual
#S14006
4/15/92
Note: If a system checker is not available, use an ohmmeter connected to the cable ends to measure its resistance. The ohmmeter reading should be 1 megohm +/-
15%. Be sure that the calibration date of the ohmmeter has not expired. If the ohmmeter reading exceeds 1 megohm by +/- 15%, replace the ground cord with a new one.
4.
Static-safe Field Procedure
(1) On reaching the work location, unfold and lay out the work surface on a convenient surface (table or floor). Omit this step if the table or floor has a built-in ESD-safe work surface.
(2) Attach the ground cord to the work surface via the snap fasteners and attach the other end of the ground cord to a reliable ground using an alligator clip.
(3) Note which boards or components are to be inserted or replaced.
(4) Power-down the system following the recommended power-down procedure.
(5) Slip on a known-good wristband, which should fit snugly; an extremely loose fit is not desirable.
(6) Snap the ground cord to the wristband. Attach the other end of the ground cord to a reliable ground using the alligator clip.
6
ESDS Manual
S14006
4/15/92
(7) The components can now be handled following the general rules as described in the instruction manual for the component.
(8) Place the component in a static-shielding bag before the ground cord is disconnected. This assures protection from electrostatic charge in case the work surface is located beyond the reach of the extended ground cord.
