Product Brief:
1C31157G03 is Emerson Ovation 48VDC wetting SOE 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‑channel sequence‑of‑events interface with built‑in 48VDC wetting supply for dry‑contact field devices
This personality module supplies internal 48VDC wetting voltage no external field power required for contact‑type signal acquisition
It captures contact‑action events with 1ms time‑stamp resolution widely used for power plant breaker status relay trip and protection fault event recording
1000VAC galvanic isolation separates 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
