Overview

The Honeywell 05701-A-0123 Single Channel Control Card is a compact, microprocessor-based module engineered for gas detection, fire safety, and environmental monitoring applications. As part of the System 57 platform, it delivers reliable control logic and alarm relay activation for individual sensor channels. Moreover, it supports Modbus TCP/RTU communication, allowing easy integration with SCADA systems and third-party controllers.

This module is built for harsh industrial environments, with a wide operating temperature range and rugged construction. Its fast response time and stable performance make it ideal for mission-critical applications where safety and uptime are paramount. Additionally, the 05701-A-0123 is often used in distributed control architectures, enabling scalable deployment across large facilities.

Technical Data

Typical Applications

• Gas Detection Systems: Controls alarm logic and relay activation for hazardous gas sensors in chemical and petrochemical plants.

• Fire Safety Monitoring: Interfaces with flame and smoke detectors to trigger alarms and suppression systems.

• Environmental Monitoring: Supports air quality and emissions control systems in regulated industrial zones.

• OEM Control Panels: Used by integrators to build modular safety and automation solutions.

• Legacy System Maintenance: Ideal for replacing aging modules in Honeywell System 57 installations without redesigning the rack.

For instance, facilities in the oil and gas sectors deploy the 05701-A-0123 to manage real-time gas concentration data and trigger alarms or ventilation systems. In addition, its Modbus support ensures easy integration with SCADA platforms and third-party controllers.
