Honeywell CC-TDI110 Digital Input Module

Technical Overview

The Honeywell CC-TDI110 is a digital input IOTA (Input/Output Termination Assembly) module designed for the Experion PKS distributed control system and C300 controller platform . This module acquires discrete AC signals from field devices such as limit switches, proximity sensors, and relay contacts, converting them into digital data for the controller .

The Honeywell CC-TDI110 features 16 optically isolated input channels, each with a dedicated LED indicator for real-time status monitoring . It supports 120 VAC nominal input with a voltage range of 90–132 VAC RMS . The module provides robust isolation of 1500 VAC RMS, effectively protecting the control system from electrical noise and voltage transients .
