750-486/040-000 4AI 0/4-20mA NE43 Ex i XTR

Important Notes 13

Protect the components against materials having seeping and insulating properties!

The components are not resistant to materials having seeping and insulating properties such as: aerosols, silicones and triglycerides (found in some hand creams). If you cannot exclude that such materials will appear in the component environment, then install the components in an enclosure being resistant to the above-mentioned materials. Clean tools and materials are imperative for handling devices/modules.

Clean only with permitted materials!

Clean housing and soiled contacts with propanol.

Do not use any contact spray!

Do not use any contact spray. The spray may impair contact area functionality in connection with contamination.

Do not reverse the polarity of connection lines!

Avoid reverse polarity of data and power supply lines, as this may damage the devices involved.

Avoid electrostatic discharge!

The devices are equipped with electronic components that may be destroyed by electrostatic discharge when touched. Please observe the safety precautions against electrostatic discharge per DIN EN 61340-5-1/-3. When handling the devices, please ensure that environmental factors (personnel, work space and packaging) are properly grounded.

Perform insulation tests with direct current (DC)!

Both the supply voltage and control voltage side are capacitively coupled to the

DIN rail. If the modules are mounted on the DIN rail, application of an AC voltage between the two potentials can lead to the destruction of the device.

Use only direct current (DC) for insulation testing.

To avoid destroying the device, discharge the device completely before applying the test voltage again.

750-486/040-000 4AI 0/4-20mA NE43 Ex i XTR

The I/O module 750-486/040-000 (4AI 0/4-20mA NE43 Ex i XTR) measures currents with standardized values of 0 … 20 mA, 4 … 20 mA and 3.6 … 21 mA

(Namur NE43) from the field range. Up to 4 currents can be measured.

This I/O module connects to 2- and 3-wire sensors. 2-wire sensors are connected via U

V

and AI and in 3-wire technic via U

V

, AI and 0 V.

The sensors are basically supplied from the I/O module's field-side power supply

The I/O module has 4 input channels for field signals. The sensors are connected to the CAGE CLAMP

®

connectors AI 1 to AI 4.

The intrinsically safe supply of the transducer is done with a noninherently shortcircuit proof transmitter supply via the connections U

V

1 or U

V

4.

The channels have a common reference potential and a shield connection.

The shield connection is fed directly to the carrier rail and contact is made automatically by snapping the module onto the rail.

The assignment of the connections is described in the “Connectors” section.

Connection examples are shown in section “Connect Devices” > … >

“Connection Example(s)”.

The Output signal is electrically isolated and will be transmitted with a resolution of 12 bits.

The field voltage and the system voltage are electrically isolated from each other.

The operational readiness and the trouble-free local bus communication of the channels are indicated via a green function LED.

A red error LED per channel indicates a wire break, a short circuit or that the signal is outside the measuring range.

The meaning of the LEDs is described in the “Display Elements” section.

Power to the internal electronics is supplied via both the internal data bus and the field supply.

The I/O module 750-486/040-000 (4AI 0/4-20mA NE43 Ex i XTR) receives the

24 V voltage supply for the field level from an upstream I/O module or from the fieldbus coupler/controller via blade-formed power jumper contacts. It then provides these potentials to subsequent I/O modules via spring-formed power jumper contacts.

Ex i XTR I/O modules shall only be supplied via “Power Supply 24 VDC

Diagn for Ex I XTR Modules”

Ex i XTR I/O modules shall only be operated with a “Power Supply 24 VDC

Diagn for Ex I XTR Modules” 750-606/040-000.

750-486/040-000 4AI 0/4-20mA NE43 Ex i XTR

Device Description 15

Do not exceed maximum current via power contacts!

The maximum current available from the “Power Supply 24 VDC Diagn for Ex i

XTR Modules” 750-606/040-000 is 1 A. Greater currents can damage the power contacts. When configuring the system, ensure that this current is not exceeded.

If exceeded, an additional 750-606/040-000 must be used.

With consideration of the power jumper contacts, the individual modules can be arranged in any combination when configuring the fieldbus node.

An arrangement in groups within the group of potentials is not necessary.

The 750-486/040-000 module can be used with the fieldbus couplers and controllers of the WAGO-I/O-SYSTEM 750 of the specified version or higher listed in the “Compatibility list” table.

Process Image

The 750-486/040-000 I/O module provides 1 status byte (8 bits) and 1 data word

(16 bits) per channel.

The I/O module supplies the input current range 0 mA … 20 mA or

4 mA … 20 mA or 3.6 … 21 mA (sensor type NAMUR NE43) at a resolution of

13 bits.

The digitalized measured value is transmitted to the process image of the coupler/controller in a data word (16 bits) as input byte “0” (low) and input byte

“1” (high). This value is mapped with a resolution of 12 bits on bit B3 ... B14.

Status information, which can be evaluated for fault detection, is contained in the two least significant bits (B0 ... B1).

In the case of a measurement underrange or overrange, bits B0 and B1 are set = 1.

Bit 2 is not defined and is not evaluated.

4.1 Overview

Process Image 37

Presentation of control/status bytes a function of fieldbus coupler/controller!

The I/O module always makes its complete process image incl. control/status bytes available to the fieldbus coupler/controller. The WAGO-I/O-CHECK commissioning tool accesses the complete commissioning process image. The fieldbus coupler/controller uses a different process image to stage cyclic process data via the fieldbus. In the other process image, depending on the fieldbus coupler/controller, the representation of control/status bytes can be suppressed.

Mounting 45

5.1 Mounting Sequence

Fieldbus couplers/controllers and I/O modules of the WAGO-I/O-SYSTEM 750 are snapped directly on a carrier rail in accordance with the European standard

EN 50022 (DIN 35).

The reliable positioning and connection is made using a tongue and groove system. Due to the automatic locking, the individual devices are securely seated on the rail after installation.

Starting with the fieldbus coupler/controller, the I/O modules are mounted adjacent to each other according to the project design. Errors in the design of the node in terms of the potential groups (connection via the power contacts) are recognized, as the I/O modules with power contacts (blade contacts) cannot be linked to I/O modules with fewer power contacts.

Risk of injury due to sharp-edged blade contacts!

The blade contacts are sharp-edged. Handle the I/O module carefully to prevent injury.

Insert I/O modules only from the proper direction!

All I/O modules feature grooves for power jumper contacts on the right side. For some I/O modules, the grooves are closed on the top. Therefore, I/O modules featuring a power jumper contact on the left side cannot be snapped from the top. This mechanical coding helps to avoid configuration errors, which may destroy the I/O modules. Therefore, insert I/O modules only from the right and from the top.

Don't forget the bus end module!

Always plug a bus end module 750-600/040-000 onto the end of the fieldbus node! You must always use this bus end module at all fieldbus nodes with the

WAGO-I/O-SYSTEM 750 XTR fieldbus couplers/controllers to guarantee proper data transfer.

For vibration loads > 4g, observe the following installation instructions:

• Use pan-head screws or blind rivets at least every 60 mm (12 mm pin

•

• spacing) to secure the DIN rail.

Make the open conductor length between strain relief and wire connection as short as possible.

Use the reinforced end stop 249-197.

5.2 Inserting and Removing Devices

Do not touch hot surfaces!

The surface of the housing can become hot during operation. If the device was operated at high ambient temperatures, allow it to cool off before touching it.

Perform work on devices only if they are de-energized!

Working on energized devices can damage them. Therefore, turn off the power supply before working on the devices.

Temperature range applies to normal operation!

XTR I/O modules may be operated below

−20 °C, but not wired and/or reconnected.

5.2.1 Inserting the I/O Module

1. Position the I/O module so that the tongue and groove joints to the fieldbus coupler/controller or to the previous or possibly subsequent I/O module are engaged.

Figure 7: Insert I/O Module (Example)

2. Press the I/O module into the assembly until the I/O module snaps into the carrier rail.

With the I/O module snapped in place, the electrical connections for the data contacts and power jumper contacts (if any) to the fieldbus coupler/controller or to the previous or possibly subsequent I/O module are established.

5.2.2 Removing the I/O Module

1. Remove the I/O module from the assembly by pulling the release tab.

6.1 Connecting a Conductor to the CAGE CLAMP

®

The WAGO CAGE CLAMP

®

connection is appropriate for solid, stranded and finely stranded conductors.

Only connect one conductor to each CAGE CLAMP

®

!

Only one conductor may be connected to each CAGE CLAMP

®

.

Do not connect more than one conductor at one single connection!

If more than one conductor must be routed to one connection, these must be connected in an up-circuit wiring assembly, for example using WAGO feedthrough terminals.

1. For opening the CAGE CLAMP

®

insert the actuating tool into the opening above the connection.

2. Insert the conductor into the corresponding connection opening.

3. For closing the CAGE CLAMP

Further information about explosion prevention can be found in section “Use in

Hazardous Environments”!

The Ex i XTR I/O module receives the 24 V voltage supply for the field level from an upstream Ex i XTR I/O module or from the “Power Supply 24 VDC Diagn for

Ex i XTR Modules” 750-606/040-000 via the power contacts used as blade contacts. It then provides this potential to subsequent I/O modules via the power contacts used as spring contacts.

6.2.1 Supplementary Power Supply Regulations

The I/O-SYSTEM 750 XTR can also be used in shipbuilding applications and onshore/offshore installations (e.g., platforms, loading facilities), as well as in the rail sector and telecontrol applications. This is possible via certification under the standards of leading agencies such as DNV GL and Lloyds Register.

For standard-compliant application of Ex i XTR modules in substation instrumentation and control, telecontrol systems, rail technology or shipbuilding certified operation, field-side power supply filters 750-624/040-001 (Field Supply

Filter 24 VDC HI NC XTR) or power supply filters 750-626/040-000 (Supply Filter

24 VDC HI XTR) are generally to be used for XTR I/O module groups

Read the current of the measurement device and I/O module.

Example:

Reference current 1 (y1)= 0.9 mA

At 1 V is x1 = 0.915 mA

6. Apply a second 1.1 kOhm resistor in series to the same I/O module channel.

Read the current of the measurement device and I/O module.

Example:

Reference current 2 (y2)= 13.7 mA

At 9 V is x2 = 13.8 mA

7. Insert all read values into the respective equations to obtain the values for the calibration gain and offset sought.

Example:

Calibration gain: m = (y2 – y1) / (x2 – x1)

 m = (13.7 mA – 0.9 mA)) / (13.8 mA – 0.915 mA) = 0.993

Calibration offset: b = (y1 / m) – x1

 b = (0.9 mA / 0.993) – 0.915 mA

= −0.008 mA

8. Enter the value calculated for calibration gain (0.993) in WAGO-I/OCHECK .

9. Convert the result for the calibration offset from milliamps to microamps.

10.

Enter the value calculated for calibration offset in microamps (−8 µA) in

WAGO-I/OCHECK .

7.3 Scaling Measured Values

User scaling serves to adjust the process values. When user scaling is used, the required accuracy of the process value resolution is changed, but not fundamentally limited. User scaling is optional.

The values for “Gain” and “Offset” are required to perform user-defined scaling.

The scaling gain is the gain factor. The scaling offset is the offset on the y axis.

When these two values are input, a scaled process value is yielded as the result.

The following general scaling equation applies:

• y2 = y1 × (Gain / 1024) + Offset

The variables have the following meaning:

Variable Meaning/function y2 y1

Unscaled process value

Offset

Scaling gain (gain factor)

Scaling offset (offset)

1024 Resolution 1/1024

The y1 value (unscaled process value) serves as the input value for the user scaling. With user scaling switched off, the y1 value is transferred unchanged to y2.

8 Diagnostics

Diagnostics 81

8.1 I/O Module Behavior in the Event of an Error

The response of the I/O module if a diagnostic is present depends on the configuration for wire break monitoring, short circuit monitoring, underrange/ overrange monitoring and upper/lower limiting value monitoring. You can activate or deactivate these diagnostics separately in WAGO-I/OCHECK (see section

“Startup” > … > “Parameterization with WAGO-I/OCHECK ”).

The I/O module only allows one error to be indicated. A dedicated bit in the status byte is assigned to each error. The associated status bit is set if an error status is detected. Certain errors cause multiple error statuses to occur. This is why error statuses are given priority levels. In the event of several errors being present, the error with the highest priority will always be displayed.

The following priority levels apply:
