Product Brief:

1C31107G02 is Emerson Ovation 16‑channel 125VDC digital input electronic module, it is G02 hardware variant of 1C31107 series DI module, specially for 125VDC field signal acquisition. It is plugged onto matched I/O base unit, mainly used for collecting 125VDC switch‑contact status signals from field relays, limit switches and auxiliary contacts. It adopts high‑speed signal‑conditioning circuit, realizes rapid signal response within 1ms, and transmits field‑device on‑off status 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 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.
