Product Brief:

1C31166G02 is Emerson Ovation enhanced serial link controller module G02 hardware revision, upgraded version compared with 1C31166G01, supports richer serial communication protocols for third‑party equipment access.

It is plugged onto matched I/O base unit provides two independent configurable serial communication ports for Ovation DCS system.

This module supports RS‑232, RS‑422, RS‑485 hardware interfaces, compatible with Modbus RTU and DNP3 protocols, widely used for data interconnection between Ovation system and field intelligent transmitters, remote RTU, auxiliary PLC subsystems in thermal power‑plant.

Rich configurable serial‑port parameters adapt different third‑party device communication requirements simplifies multi‑system interconnection engineering configuration.

1000Vrms galvanic isolation separates external serial‑device side from DCS logic backplane avoids ground‑loop interference and transient surge damage.

Built‑in communication fault diagnosis function monitors link state convenient for on‑site troubleshooting.

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
