Product Brief:

1C31157G02 is Emerson Ovation high‑voltage SOE digital input personality module G02 hardware revision works paired with 1C31127G01 electronic module

It is plugged onto I/O base together with host module defines 16‑channel sequence‑of‑events interface for 125VAC DC field discrete signal acquisition

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

It adapts 125VAC and 125VDC contact signals widely used for breaker auxiliary contacts trip relay feedback and high‑voltage cabinet status recording

1000VAC galvanic isolation separates high‑voltage field side from DCS logic backplane suppresses ground‑loop interference and transient surge 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
