Honeywell TC-FID161 24Vdc Sink Digital Input

Honeywell TC-FID161 24 Vdc Sink Digital Input Module

Product Introduction

The TC-FID161 is a 24 Vdc sink digital input module from Honeywell's C Series I/O lineup. It provides 16 non-isolated sinking channels arranged in one group. Specifically, the module mounts on standard DIN rail inside control cabinets. Engineers use this unit to monitor discrete field signals such as limit switches, relay contacts, and pushbuttons. Additionally, each channel carries a yellow status indicator for quick troubleshooting. The TC-FID161 interfaces with the controller through the Flexbus backplane and reports input states through the output image table.

Technical Specifications

ON-state voltage ranges from 10V dc minimum to 31.2V dc maximum, with 24V dc nominal. ON-state current measures 2mA minimum and 8.8mA nominal at 24V dc, topping out at 12.1mA. Meanwhile, OFF-state voltage stays at 5.0V dc maximum with 1.5mA minimum OFF-state current. Input impedance is 2.5K. Besides, the module draws 25mA maximum from the Flexbus and dissipates 6.1W at 31.2V dc. Thermal dissipation reaches 20.8 BTU/hr at the same voltage. Furthermore, dielectric withstand testing runs at 1900V dc for 1s between user and system, though no isolation exists between individual channels.

Filter times are selectable for OFF-to-ON transitions. Options include 256µs, 512µs, 1ms, 2ms, 4ms, 8ms, 16ms, and 32ms. The 256µs default is selectable through the output image table. External dc power must stay within 19.2-31.2V dc with 5% ac ripple.

Mechanical and Environmental Parameters

Dimensions measure 69mm x 94mm x 80mm (2.72in x 3.7in x 3.2in). Operational temperature spans 0 to 55°C (32 to 131°F). Storage temperature ranges from -40 to 85°C (-40 to 185°F). Relative humidity stays at 5 to 95% non-condensing. Shock ratings reach 30g peak operating and 50g peak non-operating. Vibration testing follows IEC 68-2-6 at 5g across 10-500Hz. The unit holds Class I Division 2 and Class I Zone 2 Group IIC certifications. Agency certification covers Groups A, B, C, and D.

Installation Guide

First, snap the module onto the DIN rail in its assigned slot. Next, wire field devices using 12 gauge (4mm²) stranded conductors maximum. Keep insulation at 3/64 inch (1.2mm) with a 90°C minimum temperature rating. Tighten terminal screws to 4-7 inch-pounds to ensure solid contact. Moreover, connect external dc power within the 19.2-31.2V dc range. Finally, set the input filter time in the output image table and confirm the yellow indicators respond to field signals.
