Overview Manuals Specifications Applications Configuration & Programming Firmware & Updates

Features:

  • Interface Between Connected Catalytic Gas Detectors and Central Control System
  • Combines Capability of Signal Processing with Multi-Channel Alarm Management
  • Operates in Conjunction with the Engineering Card and Optional Analogue Output Modules
The HONEYWELL 05704-A-0144 operates as the Four Channel Control Card Catalytic in a gas detection system, providing reliable control, display, and alarm facilities for up to four connected catalytic gas detectors. It continuously processes incoming signals from multiple detector channels and presents gas readings, channel status, and channel identification through the front panel backlit display. Seamless alarm indication is standard with the 05704-A-0144, however using the push-button interface will allow manual alarm reset and channel selection for use with the Engineering Card. The 05704-A-0144 has made improvements in several areas over previous control card designs in addition to incorporating microprocessor-controlled operation with fully definable software configuration.

The 05704-A-0144 provides essential control functions common to the entire gas detection system, and is a critical component of the monitoring path, directly affecting the proper, normal operation of the overall safety system. One 05704-A-0144 control card is required per four detector channels depending on the desired monitoring capacity. The 05704-A-0144 occupies a dedicated slot in the system rack and interfaces directly with catalytic input type gas detectors.

For enhanced remote monitoring applications, the 05704-A-0144 system requires optional Analogue Output Modules plugged into the control card. In addition to standard local display operation, the enhanced configuration also performs remote signal transmission. The 05704-A-0144 analogue output system executes data transfer using dedicated modules specified in the output options. Using this method, the remote monitoring system continually provides channel card readings to external control platforms. If the system requires either current source or current sink configurations, it will automatically adapt the output type per module and support integration with distributed control systems.

The 05704-A-0144 HONEYWELL Four Channel Control Card may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The Honeywell 05704-A-0144 is a specialized four-channel control card engineered for the System 57 gas detection series. This card is specifically designed to provide comprehensive control, display, and alarm functions for up to four catalytic bead gas sensors. By integrating high-density monitoring capabilities into a single module, the 05704-A-0144 allows operators to maintain a compact footprint within a 19-inch rack system while managing multiple detection points simultaneously.

In terms of technical functionality, the 05704-A-0144 features a sophisticated constant current drive, adjustable from 90mA to 315mA, ensuring compatibility with a wide range of catalytic bridge-type sensors. The 05704-A-0144 is equipped with a clear, backlit LCD that presents real-time gas concentrations through both digital numeric values and analog bargraphs. To ensure system integrity, the 05704-A-0144 incorporates built-in diagnostics, including short-circuit protection and single-bead failure detection, which minimizes downtime and prevents false readings.

This Honeywell 05704-A-0144 is specifically designed for handling the monitoring of combustible gases in hazardous industrial environments, such as oil and gas refineries or chemical processing plants. It solves the problem of monitoring multiple risk zones in tight spaces where traditional single-channel controllers would be too bulky or cost-prohibitive. By using the 05704-A-0144, facilities can centralize their safety data and respond rapidly to potential leakages, ensuring both personnel safety and regulatory compliance.

Technical notes
The 05704-A-0144 control card is specifically designed for catalytic converter gas detectors, unlike the 05704-A-0145 model which supports 4-20mA input devices. The 05704-A-0144 module effectively solves the challenge of centralized monitoring and alarm management for multiple gas detection points, providing operators with immediate visual feedback and alarm notifications when hazardous gas concentrations are detected.
