Honeywell 51304362-300 Serial Interface I/O Processor

1. Basic Model Information Part Number: 51304362-300 Generic Model: MC-PSIM11 / MU-PSIM11 Full Name: Serial Interface IOP (Input/Output Processor) Applicable System: Honeywell Experion PKS APM / HPM DCS Control System Matching FTA: Dedicated serial communication terminal assembly

Description

2. Product Function Description

This serial interface IOP is a special communication processing card independent of standard digital I/O FTA boards. It realizes serial data interaction between DCS main control cabinet and third-party field equipment, supporting RS232/RS485 serial communication protocols. It collects and forwards instrument data, PLC signals and peripheral serial device information to the Experion control network, with built-in electrical isolation between communication channels to avoid signal interference. It is widely used for interconnection with analyzers, weighing instruments, external PLCs and other serial smart devices in process industries.
