Honeywell 51304441-175 Digital Input Module Experion PKS

Honeywell 51304441-175 MC-TDID12 Digital Input Termination Module

Product Description

The MC-TDID12 (51304441-175) is a high-density Digital Input Termination Module engineered for the Honeywell Experion PKS and TDC 3000 distributed control systems. This module acts as a robust interface between field discrete devices and the controller, providing 32 independent channels for monitoring ON/OFF states from equipment such as limit switches, relay contacts, and push buttons.

Designed for mission-critical reliability, the MC-TDID12 (51304441-175) incorporates advanced galvanic isolation to protect system electronics from field-side electrical surges and noise. Its architecture supports real-time fault diagnostics, allowing engineers to maintain high system availability in complex industrial environments including petrochemical refining, power generation, and large-scale manufacturing.
