Product Brief:

1C31113G04 is Emerson Ovation 8‑channel analog input electronic module G04 hardware revision of 1C31113 series designed for ±1VDC low‑voltage transmitter signal acquisition

It is plugged onto matched I/O base unit mainly used for collecting ±1VDC output signals from field low‑range transmitters and sensor amplifiers

It adopts 13‑bit A/D chip to complete analog‑digital conversion 10Hz sampling rate meets conventional thermal‑process measurement requirements transmits processed digital data to Ovation controller via I/O bus

Built‑in digital filtering improves signal stability under complex electromagnetic interference environment

Each input channel is equipped with over‑voltage protection and signal filtering function with independent channel fault diagnosis convenient for locating abnormal field signals

1000VAC 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
