Product Brief:

1C31129G04 is Emerson Ovation SOE digital input personality module G04 hardware revision works paired with 1C31127G01 electronic module

It is plugged onto I/O base together with host module defines 16 channels for sequence‑of‑events high‑precision time‑stamped signal acquisition

This personality module is specially designed for power plant event recording captures contact‑action events with 1ms time‑stamp resolution for fault post‑mortem analysis

It supports dry contact and 0‑60VDC wet input widely used for breaker status relay trip and protection device signal recording

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

It transfers field discrete status and event timestamp data 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
