Honeywell 8C-POIL51 Digital Input Module

The Honeywell 8C-POIL51 Digital Input Module is a reliable, high-performance industrial automation component designed to capture discrete digital signals from field devices such as switches, sensors, limit devices, and relay contacts. It is part of Honeywell’s robust C300 Process Control System, which forms the backbone of the Experion Process Knowledge System (PKS).

This module is engineered for critical environments where real-time digital signal acquisition is vital. It features 16 isolated input channels, ensuring each channel operates independently, reducing the risk of signal interference and improving noise immunity. Whether deployed in oil refineries, chemical processing plants, or manufacturing environments, the 8C-POIL51 provides dependable operation with diagnostics and system integration built-in.

Its compatibility with Honeywell’s IOTA (Input/Output Terminal Assembly) architecture ensures fast installation, modularity, and seamless integration into large-scale distributed control systems (DCS).
