Product Precautions
Westinghouse 1C31122G01 provides sixteen current-sinking Ovation digital outputs for switching dc field loads and relay interfaces under controller command.
- Provides sixteen output channels for the documented digital output electronics module function.
- Handles dc load or relay-panel control through the specified Ovation I/O subsystem.
- Works with 1C31125G01, 1C31125G02 or 1C31125G03 personality module.
- The module can drive direct dc loads or operate through supported Ovation relay-panel arrangements.
The digital output electronics module belongs in the controlled Ovation I/O subsystem and works with 1C31125G01, 1C31125G02 or 1C31125G03 personality module. Its field connection, companion hardware and project configuration must be reviewed together before the channel is returned to service.
Important Notice: Use 1C31122G01 only with 1C31125G01, 1C31125G02 or 1C31125G03 personality module; verify the field interface and controlled configuration before energizing the subsystem.

Westinghouse 1C31122G01 Official Technical Reference Excerpt (PDF)Westinghouse 1C31122G01 Installation & Commissioning Guide (PDF)
The first document covers the product function, system role and technical selection. The installation guide covers identification, connection checks, commissioning and the acceptance record.
Installed-base maintenance
Restores the documented digital output electronics module position without changing the approved system architecture.
Loop or channel service
Supports verification of dc load or relay-panel control at the assigned control-system channel.
Planned replacement
Provides an exact-identity replacement path when 1C31125G01, 1C31125G02 or 1C31125G03 personality module and the field interface have been confirmed.
Commissioning support
Allows the responsible engineer to prove wiring, configuration, status and response for sixteen output channels.
Before installing Westinghouse 1C31122G01, confirm the documented system, interfaces and controlled configuration.
1
Match the complete 1C31122G01 marking to the work order and installed position before removal.
2
Confirm 1C31125G01, 1C31125G02 or 1C31125G03 personality module before making or breaking any field connection.
3
Keep the assigned dc load or relay-panel control within the documented subsystem and range.
4
Record terminal designations, polarity, common and shield treatment before disconnecting conductors.
5
Inspect module seating, connector keying, terminal condition and strain relief before power is restored.
6
Restore the controlled channel configuration, range selection and alarm or timeout behavior after installation.
7
Check local indicators and controller diagnostics for internal, communication or channel faults during commissioning.
8
Prove the intended response across sixteen output channels and record the acceptance result before release.
Technical notes
Use 1C31122G01 only with 1C31125G01, 1C31125G02 or 1C31125G03 personality module; verify the field interface and controlled configuration before energizing the subsystem.
FAQ View All FAQ
-
What output topology is used by Westinghouse 1C31122G01?The module provides sixteen current-sinking digital-output channels.
-
What field-voltage range applies to Westinghouse 1C31122G01 loads?Its documented load range is 0 to 60 V dc.
-
How much current can one Westinghouse 1C31122G01 output switch?An individual output can handle up to 500 mA, subject to the module's total fuse rating.
-
Which personality modules may accompany Westinghouse 1C31122G01?The documented subsystem uses 1C31125G01, 1C31125G02 or 1C31125G03 according to the required field interface.
-
How does the communication-timeout setting affect Westinghouse 1C31122G01?The configured timeout defines how the output module responds when controller communication is not maintained, so it must match the process fail-state design.
-
What do the front indications on Westinghouse 1C31122G01 show?A status LED is provided for each output, allowing the commanded channel state to be compared with the connected field circuit.
-
Why must total loading be reviewed even when every Westinghouse 1C31122G01 channel is below 500 mA?The per-channel limit does not override the shared fuse rating, so the combined load must remain within the documented module constraint.
-
Which checks confirm a replaced Westinghouse 1C31122G01 is controlling the correct loads?Verify all sixteen channel assignments, observe the corresponding output LEDs and prove each 0–60 V dc load under a controlled command.
