BEFORE YOU BEGIN
Do not use this product on machinery lacking effective point-of-operation
guarding. Lack of effective point-of-operation guarding on a machine can result in
serious injury to the operator of that machine.
CAUTION
EQUIPMENT OPERATION HAZARD

Verify that all installation and set up procedures have been completed.

Before operational tests are performed, remove all blocks or other temporary
holding means used for shipment from all component devices.

Remove tools, meters, and debris from equipment.
Failure to follow these instructions can result in injury or equipment
damage.
Follow all start-up tests recommended in the equipment documentation. Store all
equipment documentation for future references.
Software testing must be done in both simulated and real environments.
Verify that the completed system is free from all short circuits and grounds,
except those grounds installed according to local regulations (according to the
National Electrical Code in the U.S.A, for instance). If high-potential voltage
testing is necessary, follow recommendations in equipment documentation to
prevent accidental equipment damage.
Before energizing equipment:

Remove tools, meters, and debris from equipment.

Close the equipment enclosure door.

Remove ground from incoming power lines.

Safety Information

Regardless of the care exercised in the design and manufacture of
equipment or in the selection and ratings of components, there are hazards
that can be encountered if such equipment is improperly operated.

It is sometimes possible to misadjust the equipment and thus produce
unsatisfactory or unsafe operation. Always use the manufacturer’s
instructions as a guide for functional adjustments. Personnel who have
access to these adjustments should be familiar with the equipment
manufacturer’s instructions and the machinery used with the electrical
equipment.

Only those operational adjustments actually required by the operator should
be accessible to the operator. Access to other controls should be restricted to
prevent unauthorized changes in operating characteristics.

Overview
Overview
The Model 5502 Differential Analog input module adds eight Differential analog
inputs to the 5000 input/output system. Up to sixteen model 5502 modules may
be connected to the I/O bus, for a total of 128 analog inputs per bus. The 5502
module can be used to measure ±10V analog signals and 0-20mA analog
signals.
The 5502 module uses a 13 bit plus sign analog to digital converter (ADC). A
single chip microcontroller with integral watchdog timer operates the module and
communicates over the I/O bus.
Inputs are fuse and transient protected and optically isolated from the main logic
power and the other analog inputs.

Installation
Installation
The installation of the 5502 module requires mounting the module on the 7.5mm
by 35mm DIN rail and connecting the module to the system I/O Bus. Refer to the
System Configuration Guide, at the beginning of this manual, for complete
information on system layout, I/O Bus cable routing and module installation.
Field Wiring
The 5502 module provides eight Differential analog inputs. Figure 1: Typical
5502 Field Wiring shows how to wire the inputs.
Screw termination style connectors are used for termination of field wiring. They
accommodate solid or stranded wires from 22 to 12 AWG.
The connectors are removable. This allows module replacement without
disturbing the field wiring. Leave enough slack in the wiring for the connector to
be removed.
Remove power before servicing unit.
To remove the connector:

Pull the connector upward from the board. Apply even pressure to both ends
of the connector.
To install the connector:

Line up the pins on the module with the holes in the connector.

Push the connector onto the pins. Apply even pressure to both ends on the
connector.

Installation
Address Selection
The 5000 I/O bus will support a maximum of twenty I/O (input/output) modules.
5000 I/O module types may be combined in any manner to the maximum
supported by the controller used. The types of input and output modules
available are:

Digital Input modules

Digital Output modules

Analog Input modules

Analog Output modules

Counter Input modules
Each type of I/O module, connected to the I/O bus, has a unique I/O module
address. Different types of I/O modules may have the same module address.
The address range supported by the SCADAPack controller module may restrict
the I/O module address range. Refer to the controller manual for the maximum
address supported.
The three address switches in the dip switch package SW1 labeled 1, 2, 4 and 8
set the module address. To set the address:

Open the four switches by sliding the actuators to the left side of the switch.

Close the switches by sliding the actuators to the right such that they total the
desired address.
Figure 2: 5502 Differential Analog Input Module Address Switches shows
the switch setting for the 16 possible module addresses.

Voltage or Current Range Selection
The 5502 module measures voltages in the range of –10V to +10V with respect
to the –ve input of the measuring channel. Currents in the range of -20mA to
+20mA can be measured by on any of the inputs by inserting an onboard 250Ω
resistor in current loop. The resulting voltage input will be –5V to +5V. This
resistor is added by closing the appropriate switch labeled 0 through 7 in the dip
switch package SW2. Close the switch by sliding the actuator up to the ON
position.
AC Rejection Selection
The 5502 module samples the analog inputs several times for optimum rejection
of AC noise. 60 Hz. AC rejection is obtained when the actuator for the switch
labeled 50/60 is in the left position. 50 Hz. AC rejection is obtained when the
actuator for the switch labeled 50/60 is in the right position.

Condition
Action
Inputs read near 0.
Input voltages read
slightly low.
Reading is constant.
Check and if necessary replace the input fuse.
Check SW2 and check the switch is in the
voltage position.
Check that the analog input is not forced.
Fuses
Each input is has an 1/8A fuse. This fuse will blow when the input voltage
exceeds approximately 12V. The fuse is Littelfuse NANO-SMF 1/8A Fast-Acting
fuse. Replacement fuses are available from Control Microsystems.

Operation and Maintenance
Calibration
The 5502 module is calibrated and burned in at the factory. It does not require
periodic calibration. Calibration may be necessary if the module has been
repaired as a result of damage.
There is one potentiometer for calibration of the analog inputs. The GAIN
potentiometer (R14) adjusts the gain.
Calibration requires that you read the converted value from the module using a
communication controller, SCADAPack or TeleSAFE Micro16 controller module.
Refer to the controller module manual for details.
To calibrate the module:

Select an input and check the associated switch in the dipswitch package
SW2 is OFF.

Short the selected analog input.

Adjust the ZERO potentiometer (R20) until a reading of 0 is obtained.

Apply a voltage between 9 and 10 Volts on the selected analog input.

Calculate the correct reading for the applied voltage using the formula:

reading =(32768 X voltage/10)
Adjust the GAIN potentiometer (R19) until the correct reading is obtained.
The calibration may be verified by applying other voltages or voltages of the
opposite polarity to the other input terminals. Use the formula above to determine
the correct reading for each input voltage.
