Technical Specifications

FAQ

1. HART Capability
   The 1C31129G05 is a legacy analog output module without integrated HART. Use 5X00063G01 or 5X00589G01 for HART-enabled applications.
2. Bipolar Voltage Output
   Certain revisions support −10 to +10 VDC output. The configuration software sets the output mode.
3. Revision Differences
   G05 denotes a hardware revision with improved diagnostics and expanded voltage range. G03 and G04 are earlier revisions with reduced feature sets.
4. Ovation 3.x Compatibility
   The module is compatible with Ovation 3.x software using the appropriate personality file. Install the latest I/O personality library on the engineering station.

Installation Guide

• Step 1: De-energize the I/O branch. Remove the old module by releasing retention tabs.
• Step 2: Inspect the backplane connector for bent pins. Install 1C31129G05 into the matching keyed slot.
• Step 3: Connect field wiring. For 4–20 mA, wire the actuator across channel + and −. For voltage output, connect to Vout and COM.
• Step 4: Download the personality file from the Emerson support site if it is not present in the local library.
• Step 5: Commission channels one-by-one using the Ovation loop-check utility.

Selection Tips

Use 1C31129G05 for legacy Ovation systems requiring 4-channel analog output without HART overhead. It is cost-effective for basic valve and drive control. For HART diagnostics or higher resolution, migrate to the 5X00063G01 series. Cross-check revision compatibility with the existing I/O base.
