Honeywell 51303932-476
Overview:
The Honeywell 51303932-476 (MC-TSIM12) is a serial device interface and field termination assembly (FTA) designed for Honeywell’s industrial distributed control systems such as TDC 3000 and Experion PKS. It enables high-reliability data exchange and protocol conversion between the control system and third-party asynchronous serial devices (smart instruments, analyzers, PLCs, variable frequency drives) that support the Modbus RTU protocol. Its superior EMI and surge protection design ensures safe real-time data transmission in harsh industrial sites.
