Honeywell 51304431-200 240Vac Digital Input FTA

1. Basic Model Information Part Number: 51304431-200 Common Model: MU-TDIA62 Full Name: 32-Point Redundant AC Digital Input FTA, Screw Terminal Applicable System: Honeywell TDC3000 / TPS UCN DCS Control System Matching Main Card: MU-DIA62 32-Channel Redundant AC Digital Input IOP Card

Description

2. Product Function Description

This field termination assembly is specially matched with MU-DIA62 AC digital input IOP card, dedicated to collecting 120/240VAC switch status signals from on-site limit switches, valve position feedback and interlock devices. It adopts anti-loose screw terminal design, supports full redundant channel configuration to enhance system safety and continuous operation capability. Built-in surge suppression, RC signal filtering and channel isolation circuits effectively restrain electromagnetic interference and ground loop noise, preventing high AC field signals from damaging the main IOP card. It is suitable for high-vibration continuous production sites in chemical, power and oil & gas industries.
