EMERSON 1C31166G02
Product Name
Emerson 1C31166G02 Ovation Serial Link Controller
Product Overview
The 1C31166G02 is an Ovation serial-link-controller electronics module. It interfaces an Ovation controller with third-party devices through a serial communication personality module. The module is one element of a three-part assembly: a DIN-rail-mounted base unit, the 1C31166G02 electronics module, and a personality module that determines the physical serial interface and connector layout.

Functional Features
Serial communication interface between an Ovation controller and third-party devices
Compatible with RS-232, RS-485 and RS-422 through the appropriate personality module
Programmable serial port settings
DB9 programming and applications connectors
Local buffering and serial processing independent of the main controller
Material Composition
Electronics module: industrial printed-circuit assembly with metal and moulded enclosures
Base unit: metal DIN-rail mounting chassis
Connectors: DB9 serial connectors on the personality module
Structural Features
Electronics module inserts into the base unit
Personality module mounts separately and provides the physical connectors
Removable personality module determines RS-232 or RS-485/422 operation
Terminal-block option on the base unit for longer serial cable runs
Working Principle
The electronics module communicates with the Ovation controller across the Ovation I/O bus. The selected personality module converts the internal link to the required serial electrical standard. The module formats and buffers serial data, manages the selected baud rate, and transfers information between the Ovation controller and the connected device.
Application Scenarios
Connecting Ovation controllers to third-party PLCs
Communication with analytical instruments
Interfaces to custom electronics
Legacy Ovation system expansion
RS-232 links to programming or diagnostic equipment
Installation Requirements
Install the required personality module before inserting the electronics module
Insert the electronics module into the base unit
Mount the base unit on a standard DIN rail
Match the personality module to the required serial interface: RS-232 or RS-485/422
Use a Group One personality module for RS-232 communication
Use a Group Two personality module for RS-485/422 communication
Connect field wiring through the DB9 connector or base-unit terminal block
Keep CE-mark applications-port cables shorter than 10 metres
Use RS-485/422 for longer cable runs
Usage Notes
Do not use an RS-485/422 personality module where RS-232 is required, and vice versa
Verify the personality-module selection before system commissioning
The G02 designation identifies the electronics-module revision
Availability is limited through factory-refurbished and new-surplus channels
