More Information

Overview Manuals Applications Compatibility Diagnostics Safety

Features:

  • Provides sixteen differential digital-input channels for 125 VAC or 125 VDC field signals.
  • Uses opto-isolated field circuitry with 2000 VAC isolation from the logic side.
  • Supports an unfused cavity insert or an individually fused personality-module arrangement.
The current ordering configuration is 1C31232G03, the 125 VAC/VDC differential electronics module for Emerson Ovation Compact Digital Input assemblies.

In its intended system role, the module converts sixteen isolated high-voltage field states into digital indications used by Ovation control logic and operator diagnostics.

Before installation, confirm the base unit, field supply, terminal pairing, fusing method, hazardous-voltage labels, and configuration-register settings against the project drawings.

Availability is subject to Apter Power inventory and sourcing confirmation.

  • Monitors high-voltage breaker, contactor, valve, and auxiliary-equipment status contacts in Ovation I/O assemblies.
  • Acquires differential 125 VAC or 125 VDC field states where isolated paired input wiring is required.
  • Supports separately protected field circuits when the individually fused personality-module arrangement is installed.
  • The G03 electronics configuration is intended for the 125 VAC/VDC differential-input arrangement in Ovation Compact I/O.
  • The 1C31238H01 cavity and foam insert supports differential wiring when individual on-board fuses are not required.
  • The optional 5X00034G01 personality module provides sixteen individually fused inputs supplied from a common external source.
  • Internal module operating faults are reported through the module diagnostic interface for maintenance assessment.
  • The configuration and status register at address 13 decimal controls configured state and reports module status.
  • The blown-fuse-enable bit must remain cleared because differential configurations do not use the single-ended fuse diagnostic.
  • Hazardous-voltage warning labels are required on the applicable base unit or fused-input branch before energized service.
  • External fusing or current limiting is recommended on hazardous field inputs when the fused personality module is not installed.
  • For CE installations, route and ground field wiring at the cabinet entry in accordance with the Ovation system guidance.
Description
1C31232G03 is the 125 VAC/VDC differential electronics module in the Emerson Ovation Compact Digital Input family. It monitors sixteen isolated field states for use by controller logic and operator diagnostics.

The module uses opto-isolated field circuits and supports either the 1C31238H01 cavity insert or the 5X00034G01 individually fused personality module. Its differential front end accepts reversible input polarity at the paired terminals.

This configuration suits high-voltage status and interlock signals in Ovation I/O assemblies where channel isolation and traceable wiring are required. Selection depends on the installed base unit, field supply, fusing method, and project safety drawings.

What differentiates 1C31232G03 from the other 1C31232 module groups?
1C31232G03 is the 125 VAC/VDC differential-input electronics configuration; other 1C31232 groups use different voltage ranges or channel arrangements.
Which personality hardware can be used with 1C31232G03?
Use the 1C31238H01 cavity and foam insert for unfused differential wiring or the 5X00034G01 personality module for sixteen individually fused inputs.
Where is 1C31232G03 normally applied in an Ovation system?
It is applied to isolated high-voltage status and interlock signals that require sixteen differential 125 VAC or 125 VDC input channels.
Is 1C31232G03 currently available for quotation?
Apter Power can check current sourcing, price, lead time, and delivery options for the exact G03 configuration without implying OEM stock.
What must be checked before replacing 1C31232G03?
Confirm the complete G03 suffix, base unit, terminal mapping, field supply, fusing method, warning labels, and configuration-register settings.
Which records should accompany an inquiry for 1C31232G03 documentation?
Provide the nameplate photo, Ovation I/O drawing, installed cavity or personality-module number, field voltage, required quantity, and delivery destination.
