Product Brief:

1C31181G03 is Emerson Ovation multi‑mode media MAU personality module G03 hardware revision, works paired with 1C31179 series MAU electronic main module.

It is plugged onto I/O base together with host module, supports copper twisted‑pair and fiber‑optic two‑kind transmission media, can adapt different field wiring distance requirements.

This personality module brings flexible deployment options for thermal‑power‑plant remote I/O subsystem, can select corresponding transmission medium according to on‑site interference environment and transmission distance.

1500V galvanic isolation separates remote bus side from DCS logic backplane, suppresses ground‑loop interference and transient surge damage.

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

Shares hot‑swap, link diagnosis and surge‑suppression features from matched MAU electronic module.

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

Please confirm matching host MAU electronic module model before purchase.

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