TC-TDID72 Honeywell Experion PKS Digital Input Module

Honeywell MC-TDID72 51303928-150 Digital Input PC Board Module

Product Description

The MC-TDID72 (51303928-150) is a high-density digital input module designed for the Honeywell Experion Process Knowledge System (PKS) and TPS/TDC 3000 Distributed Control Systems (DCS). Operating as a key component of the Series MC I/O family, this module is engineered to monitor a vast array of discrete field devices including limit switches, push buttons, and safety interlock contacts.

The MC-TDID72 (51303928-150) Rev-F version provides 32 isolated digital input channels (notably distinct from the 72-channel numbering nomenclature, which often refers to the associated FTA density in specific rack configurations). Each channel is equipped with galvanic isolation to protect the system backplane from field-side electrical surges and noise. With a fast response time of less than 25 milliseconds and built-in LED diagnostics, this PC board ensures deterministic signal acquisition and simplified troubleshooting for mission-critical industrial processes.
