The TC-IDJ161 is a high-density 16-channel digital input (DI) module designed for the Honeywell Experion PKS Series C I/O platform. It interfaces directly with the C300 controller architecture to monitor dry contacts and 24V DC discrete signals from field devices such as limit switches, pushbuttons, auxiliary contacts, and relay outputs.
Engineered for industrial environments, the module provides channel-to-logic galvanic isolation and advanced signal conditioning to ensure noise immunity and reliable status detection. Integrated diagnostics continuously monitor module health and input status, supporting high-integrity process control applications.
Its compact form factor enables dense cabinet installation while maintaining proper thermal performance within Series C I/O assemblies.

Motor Starter Status Monitoring – Feedback from auxiliary contacts.
Valve Position Indication – Open/close confirmation signals.
Safety Interlocks – Integration of permissive and shutdown signals.
Discrete Process Monitoring – Pushbuttons, limit switches, and relay contacts.
High-Density DCS Panels – Optimized for compact Series C I/O cabinet layouts.
Does TC-IDJ161 require a separate termination assembly?
Yes. The module installs onto a compatible Honeywell Series C I/O Termination Assembly (IOTA), which provides field wiring connections.
Can it detect open-wire faults?
As a standard digital input module, direct open-wire detection is not native; however, when configured within Experion PKS and combined with appropriate field wiring practices, signal discrepancies can be identified through system diagnostics.
