GE IC200ALG331 Analog Output Module
In current mode, a separate power supply may be required for
isolated inputs.
Module features include:
Four isolated 4-20mA current output channels
Software configuration, no jumpers or switches
Sixteen bit converter resolution
High accuracy factory calibration
The following features are software-configurable:
Per-channel selection of 4-20mA current or +/–10V voltage outputs
Selection of default/hold last state operation
Per-channel selection of default values
Per-channel selection of under-range and over-range
diagnostics levels
Per-channel selection of alarm levels
Per-channel scaling
Field re-calibration on command
Host Interface_______________________________________
The module receives 4 words of analog output data from the system.
Diagnostics ________________________________________
The module reports High/Low Limit, Over/Underrange, Open Wire,
Loss of Field Power Supply, and Non-volatile memory fault
diagnostics.
LED Indicators ______________________________________
The green FLD PWR LED indicates the presence of both logic
power and field power for the analog field-side circuits. It does not
indicate the presence of other supplies such as current loop supplies
on output points. The absence of either backplane or field power
turns off the FLD PWR LED.
The OK LED indicates module status:
On green indicates normal operation.
Flashing green indicates boot mode or update
Flashing amber indicates self-diagnostic error.
Off indicates no 3.3V power
Note that this module is the only one that has its OK LED located
before the FLD PWR LED in the A slot.

Preinstallation Check
Carefully inspect all shipping containers for damage. If any equipment is
damaged, notify the delivery service immediately. Save the damaged
shipping container for inspection by the delivery service. After unpacking
the equipment, record all serial numbers. Save the shipping containers
and packing material in case it is necessary to transport or ship any part
of the system.
Field Wiring Terminals
Terminal assignments for the module are shown below.

A2 Shield Ground B2 I1-
A3 No connection B3 V1+
A4 Shield Ground B4 V1-
A5 No connection B5 I2+

A15 No connection B15 V4+
A16 Shield Ground B16 V4-
A17 No connection B17 DC -
A18 No connection B18 DC+
A 24 volt power supply must be connected to B17 and B18 to
operate the module.
Voltage outputs are powered from the module. For each channel, V+
is positive with respect to V- when the channel’s output data is
positive.
Current outputs act as current regulators and require a supply to
power the load. The current loop can be connected either as a
current source or as a current sink to the load.
The loads are isolated if the loop supply is isolated. However, if the
module supply is also used as the loop supply, the loads are not
isolated.
Wiring Connections for Carriers with Two Rows of Terminals
Shielded twisted pair cable is recommended for the analog channel
connections.
If the module is installed on a Terminal-style I/O Carrier or a Compact
Terminal-style I/O Carrier, the cable shield can be connected directly to
the carrier.
If the module is installed on a Connector-style I/O Carrier, the cable
shield can be connected directly to an Interposing Terminal. A shielded
interposing cable (shielded cables are available separately) must be
used between the Connector-style I/O Carrier and the Interposing
Terminal.
An Auxiliary I/O Terminal Strip can also be added to the Interposing
Terminal if additional shield connections are required.
