Product Brief:

1C31110G03 is Emerson Ovation 16‑channel contact wetting SOE digital input electronic module, it is G03 hardware revision of 1C31110 series SOE module, specially designed for dry‑contact field signal acquisition without external field power supply. It is plugged onto matched I/O base unit, mainly used for collecting dry‑contact status signals from field relays, breaker auxiliary contacts and limit switches. The module integrates 48VDC contact wetting voltage internally, no need to configure external field power source for dry‑contact loop. It provides 1ms high‑precision event time‑stamp function, accurately records the occurrence time of field equipment state changes for post‑fault analysis. It adopts high‑speed signal‑conditioning circuit, realizes rapid signal response within 1ms, transmits field‑device on‑off status and SOE event data to Ovation controller via I/O bus. 1500V RMS isolation is arranged between field‑side loop and system side, effectively restraining common‑mode interference and surge impact from field equipment. Each channel supports independent fault diagnosis for open‑circuit and short‑circuit, convenient for quickly locating wiring and field‑device faults. The module supports hot‑swap operation, can be replaced online without system shutdown for convenient site maintenance. This is EOL discontinued spare part,widely used for maintenance and renovation of thermal power plant Ovation DCS system. Please confirm matched I/O base unit before purchase. Strict ESD anti‑static protection shall be followed during installation and replacement.
