Description

The Honeywell TC-IDJ161 (TK-IDJ161) is a 16-point isolated discrete input module engineered for industrial control systems. It provides reliable digital signal acquisition for PLCs and process automation platforms operating at a nominal voltage of 24 VDC. Each input channel is individually isolated, delivering channel-to-channel and user-to-system electrical isolation to protect automation infrastructure from ground loops, voltage transients, and field interference.

Features

  • 16 Individually Isolated Channels: Complete channel-to-channel and user-to-system isolation for enhanced transient protection and noise immunity.
  • Wide On-State Operating Range: Accepts field input signals ranging from 10 VDC to 30 VDC.
  • Programmable Filter Delays: Features selectable Off-to-On (1 ms, 2 ms) and On-to-Off (1, 2, 9, 18 ms) digital delay settings to suppress field contact bounce.
  • IEC Type 1+ Input Compatibility: Designed to interface seamlessly with standard industrial discrete sensing devices and switches.
  • Robust Transient Handling: Designed with 250 mA peak inrush current capacity (decaying to <37% within 22 ms without activating input state).

Applications

  • Distributed Control Systems (DCS) and Programmable Logic Controllers (PLC)
  • Industrial discrete field signal monitoring and event logging
  • High-noise environments requiring individual channel galvanic isolation
  • Sensing systems utilizing proximity switches, pushbuttons, and auxiliary contacts

Installation Guidelines

  • Terminal Block Assembly: Connect field wiring to the compatible TC-TBCH 36-position terminal block prior to seating onto the module frame.
  • Wiring & Noise Mitigation: Route low-voltage 24 VDC input signal cables separately from high-voltage AC lines and high-current power cables to minimize electromagnetic interference.
  • System Grounding: Ensure proper cabinet and chassis grounding to maintain high isolation integrity and protection against system-level electrostatic discharge.
  • Heat Dissipation: Ensure adequate enclosure ventilation to maintain optimal operational temperatures under maximum power dissipation conditions (5.0 W max).
