Features:

  • Interface Between the Connected Gas Detector and the 5701 System Control Loop
  • Combines Capability of Signal Processing with Alarm and Display Functions
  • Operates in Conjunction with a Wide Range of Connected Gas Detectors and Application Requirements
The Honeywell 05701-A-0301 Single Channel Control Card operates as the core processing unit for a single loop of gas detection within the 5701 system, providing reliable control, display and alarm facilities for a connected 4-20mA gas detector. It continuously processes the incoming sensor drive module signal, displays the signal level on the front panel liquid crystal display, and compares the signal level with pre-defined alarm limits. When the pre-defined alarm limits are exceeded, the 05701-A-0301 raises alarms by lighting up front panel LEDs and operating optional connected relays, while simultaneously informing other cards with the alarm status information. The 05701-A-0301 also performs self-validation of its circuit components, software operation and the condition of the sensor. The operation of the 05701-A-0301 is microprocessor controlled and is fully definable for a wide range of connected gas detectors and application requirements, with the software configuration setup stored in an EEPROM.

The 05701-A-0301 provides essential control functions for a single gas detection channel, and is a critical component of the safety monitoring path, directly affecting the proper, normal operation of the overall gas detection system. One 05701-A-0301 control card is required per gas detector channel. The 05701-A-0301 occupies a single slot in the system rack and features a front panel display indicating the gas reading and channel status, with LEDs used for alarms and a push-button provided for resetting the alarms and selecting the card for use with the Engineering Card.

For applications requiring remote output of channel card readings, the 05701-A-0301 supports an optional Analogue Output Module that can be plugged into the single channel control card. In addition to standard alarm and display operation, the 05701-A-0301 performs continuous self-validation to ensure reliable gas detection performance. The 05701-A-0301 executes alarm logic using the internal microprocessor controlled circuitry specified in the control card design. Using this method, the 05701-A-0301 continually monitors the health of the connected sensor and its own circuit components. If the system detects that the gas concentration has exceeded pre-defined alarm limits, it will automatically raise the alarms, inform other cards with the alarm status information, and display the event on the front panel liquid crystal display.

The 05701-A-0301 Honeywell Single 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 05701-A-0301 Single Channel Control Card is a microprocessor-controlled module designed to provide comprehensive control, display, and alarm facilities for a single connected gas detector. As a core component of the System 57, the 05701-A-0301 is specifically engineered to handle the complexities of 4-20mA sensor signals. This 05701-A-0301 unit is designed to solve the problem of real-time monitoring in hazardous environments by processing incoming signals from a sensor drive module and displaying accurate gas readings on its front-panel liquid crystal display.

The 05701-A-0301 solves the critical issue of rapid hazard response through its sophisticated alarm management system. This 05701-A-0301 model constantly compares incoming signal levels with pre-defined alarm limits stored in its internal EEPROM. When these limits are exceeded, the 05701-A-0301 immediately triggers visual front-panel LEDs and can operate optional connected relays to initiate safety protocols. Furthermore, the 05701-A-0301 enhances system-wide safety by informing other connected cards of the current alarm status, ensuring a coordinated response across the entire control network.

In demanding industrial applications, such as offshore oil platforms or chemical processing plants, the 05701-A-0301 is used to maintain continuous system integrity through its self-validation features. The 05701-A-0301 addresses the problem of equipment reliability by automatically monitoring its own circuit components, software operations, and the physical condition of the connected sensor. For applications requiring remote data logging, the 05701-A-0301 can be fitted with an optional Analogue Output Module, allowing the 05701-A-0301 to transmit channel readings to external monitoring systems.
