Introduction
The Honeywell International Inc. 8C‑POIL51 Digital Input Module is a compact industrial I/O component used in Honeywell automation systems to acquire digital (binary) signals from field devices such as switches, contacts, and discrete sensors. These signals are then communicated to the automation controller for monitoring and control operations.
With dimensions of 120 × 30 × 25 mm (H × W × D) and a weight of 0.15 kg, this module is lightweight and well‑suited for installation in control cabinets or I/O racks where discrete signal acquisition is needed.
