Product Brief:

1C31113G01 is Emerson Ovation 8‑channel low‑voltage analog input electronic module, specially designed for millivolt‑level weak signal acquisition. It is plugged onto matched I/O base unit, mainly used for collecting ±20mV millivolt signals from field thermal resistance, strain gauge and low‑voltage transmitters. It adopts 13‑bit high‑precision A/D chip to complete analog‑digital conversion, transmits processed digital data to Ovation controller via I/O bus. Each input channel is equipped with over‑voltage protection and signal filtering function, with independent channel fault diagnosis, convenient for locating abnormal field signals. 1500V RMS isolation is arranged between field‑side loop and system side, effectively restraining common‑mode interference and surge impact. 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.
