Product Brief:

1C31174G04 is Emerson Ovation remote‑power 4‑20 mA loop interface personality module G04 hardware revision, works paired with Ovation analog I/O electronic main module。

It is plugged onto I/O base together with host module, defines hardware interface for 4‑20 mA analog input signal, this personality module does not provide internal loop power, field transmitters must adopt external remote power supply mode.

It is widely used for thermal‑power‑plant pressure, flow, liquid‑level measuring loops, suitable for field instruments equipped with independent external power supply.

1000VAC galvanic isolation separates field instrument side from DCS logic backplane suppresses ground‑loop interference and transient surge damage.

It transfers field 4‑20 mA current signals to host electronic module for A/D conversion and backplane data transmission.

No extra software configuration required after correct physical installation, host module identifies personality hardware automatically.

Shares hot‑swap, channel diagnosis and surge‑suppression features from matched analog I/O electronics module.

This is EOL discontinued spare part widely used for maintenance and renovation of thermal power plant Ovation DCS system.

Please confirm matching host module model before purchase.

Strict ESD anti‑static protection shall be followed during installation and replacement.
