3. Product Overview

The 51303932-476 is a single-channel serial FTA terminal board (MC-TSIM12) for Honeywell Experion PKS DCS systems. It converts the internal controller bus signal into standard Modbus RTU serial communication, supporting both RS232 and RS485 physical layers for connection to third-party field instruments, drives, meters and slave controllers. The conformal coating protects the circuit board from moisture and dust in industrial cabinet environments. This FTA board handles all field wiring termination for the serial interface IOP, isolates field serial signals from the backplane, and supports multi-drop RS485 networks. It is widely used to integrate Modbus devices into DCS control systems in oil & gas, chemical, power and petrochemical plants.
