Honeywell 8C-POIL51 Digital Input Module

Product Introduction

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).

Product Specifications

Product Applications

The 8C-POIL51 Digital Input Module is extensively deployed across a variety of industrial environments that require reliable digital signal acquisition and monitoring:

• Oil & Gas Facilities: Monitoring valve positions, flow switches, emergency shutdown systems (ESD).

• Petrochemical Plants: Capturing limit switch status and interlocks for process control.

• Power Generation: Detecting breaker positions, status inputs from auxiliary systems.

• Pharmaceutical Manufacturing: Monitoring sensor feedback in cleanroom automation.

• Food & Beverage Processing: Capturing start/stop signals from distributed control buttons.

• Water Treatment Plants: Integrating pump and level switch statuses into SCADA systems.

• Mining Operations: Rugged environments requiring isolated input sensing for relays and contactors.

Product Advantages
