Honeywell TC-FID321 – 24 Vdc Sink Digital Input

Overview

The TC-FID321 is a 32-channel digital input module designed for industrial automation systems. It supports a 24 VDC sinking configuration and is ideal for applications requiring reliable input processing, such as control panels, machinery, and automation systems.

Key Features:

• 32 sinking digital inputs, organized in 2 groups of 16 channels.
• Compatible with 19.2Vdc to 31.2Vdc external power.
• High current handling with 2mA minimum, 4.1mA nominal, and 6.0mA maximum ON-state current.
• Selectable input filtering time for both ON to OFF and OFF to ON transitions (ranging from 0.25ms to 32ms).
• Status indicators for each of the 32 channels.
• DIN-rail mountable, ensuring easy installation in industrial control cabinets.
