Product Brief:
1C31110G02 is Emerson Ovation 16‑channel differential SOE digital input electronic module, G02 hardware revision of 1C31110 series, designed for 125VDC differential signal SOE event recording. It is plugged onto matched I/O base unit, mainly used for collecting 125VDC differential switch‑contact status signals from field relays, breaker auxiliary contacts and high‑voltage limit switches. The module provides 1ms high‑precision event time‑stamp function, accurately records the occurrence time of field equipment state changes for post‑fault analysis. Differential input architecture greatly improves common‑mode interference suppression capability, suitable for harsh high‑voltage field environment. 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 surge impact from high‑voltage 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.
