Honeywell 51304431-100 240Vac Digital Input FTA

1. Basic Model Information Part Number: 51304431-100 Generic Model: MU-TDIA22 Full Name: 32-Point Redundant DI FTA 240Vac Compression Terminal Applicable System: Honeywell TDC3000 / TPS UCN DCS Control System Matching Main Card: MU-DIA22 32-Channel AC Digital Input IOP Card

Description

2. Product Function Description

This dedicated field termination assembly is exclusively matched with MU-DIA22 AC digital input IOP card, designed for collecting 120/240VAC on-off status signals from field instruments and switches. It adopts compression spring terminals for fast wiring without screwdrivers, supports full redundant channel configuration to improve system reliability. Integrated surge suppression, signal filtering and channel isolation circuits effectively eliminate electromagnetic interference and ground loop noise, preventing high-voltage field signals from damaging the main IOP card. Widely used in chemical, power, oil & gas and other continuous process industrial sites with AC switch signal collection demands.
