Product Brief:
1C31181G04 is Emerson Ovation single‑mode fiber‑media MAU personality module G04 hardware revision, must be paired with 1C31179G02 MAU electronic module.
It is plugged onto I/O base together with host electronic module, provides physical single‑mode fiber‑optic media interface for remote I/O subsystem.
Adopting single‑mode optical fiber transmission, it supports ultra‑long‑distance signal transmission with excellent anti‑interference capability, suitable for thermal‑power‑plant sites where remote I/O nodes are extremely far away from main control cabinet.
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 1C31179G02 host module model before purchase.
Strict ESD anti‑static protection shall be followed during installation and replacement.
