Product Brief:

1C31129G03 is Emerson Ovation digital input personality module G03 hardware revision works paired with 1C31127G01 electronic module

It is plugged onto I/O base together with host module defines 16 channels with built‑in 24VDC wetting supply for dry‑contact field devices

This personality module provides internal wetting voltage no external field power required for contact‑type sensors and switch contacts

It is widely applied for thermal‑process valve position feedback relay contact status and local switch signal acquisition

1000VAC isolation separates field side from DCS logic backplane suppresses ground loop interference and transient voltage damage

It transfers field discrete status to host electronic module for signal filtering and backplane data transmission

No extra software configuration required after correct physical installation host module identifies personality hardware automatically

Shares hot‑swap channel diagnosis and surge suppression features from matched 1C31127G01 electronic module

This is EOL discontinued spare part widely used for maintenance and renovation of thermal power plant Ovation DCS system

Please confirm matching host module model before purchase

Strict ESD anti‑static protection shall be followed during installation and replacement
