Product Overview

The MC-TDID12 (51304441-175) is a high-density Digital Input (DI) module designed for the Honeywell TDC 3000 and Experion® PKS Distributed Control Systems. This module provides 32 independent channels for acquiring discrete signals from field devices such as pushbuttons, limit switches, and relay contacts. Operating at a nominal 24 VDC, the MC-TDID12 acts as an authoritative interface between field hardware and the controller, ensuring that binary plant states are captured with high precision. Its ruggedized Series C construction and galvanic isolation between the field and system logic make it a mechanical necessity for maintaining system integrity in high-availability industrial environments.
