Honeywell 05701-A-0328 Analysis Relay Card

Product Dimensions：

The Honeywell 05701-A-0328 is a high-density, 4-channel control card belonging to the iconic System 57 gas detection family. It is designed to provide comprehensive monitoring of gas sensors in a compact, rack-mounted format, making it a staple for industrial safety systems.

Product Detailed Description

The 05701-A-0328 acts as the “brain” for up to four individual gas detectors. It receives analog signals (typically 4–20 mA) from field-mounted sensors, processes the data, and displays real-time gas concentrations. The module is designed to be housed in a System 57 rack, where it interfaces with a backplane to provide power to sensors and trigger alarm relays.

Technical Parameters

Product Advantages

• High Density: By packing four channels into a single module width, it reduces the required rack space by 75% compared to traditional single-channel cards.
• Independent Channel Logic: Each channel is fully independent; a failure or maintenance on one sensor does not affect the monitoring capabilities of the other three.
• Easy Visualization: Each channel features its own dedicated multi-segment LCD, allowing operators to see the status of all four sensors simultaneously without scrolling through menus.
• Rugged Reliability: The System 57 is proven in harsh environments, offering stable performance for mission-critical life safety applications.

Important Considerations & Precautions

• Backplane Wiring: Ensure your System 57 rack backplane is wired specifically for a 4-channel card. Using a 4-channel card in a slot wired for a single-channel card will lead to incorrect signal processing.
• Sensor Compatibility: The card is optimized for 4–20 mA signals. If using 3-wire or 2-wire sensors, verify the jumper settings on the card to ensure proper power delivery.
• Calibration: While the card processes the signal, the actual “accuracy” depends on the field sensor. Regular “bump testing” and system-wide calibration are required for safety compliance.
• Heat Dissipation: In fully populated racks, ensure there is adequate ventilation within the control cabinet to prevent heat buildup from the combined power draw.

Product Applications

The 05701-A-0328 is used wherever multiple points of gas detection are required in a centralized location:

• Oil & Gas: Monitoring for H_2S and combustible gases on offshore platforms and in refineries.
• Chemical Processing: Detecting toxic leaks in large-scale storage areas or production lines.
• Marine: Engine room and cargo hold monitoring for flammable vapors.
• Water Treatment: Detecting Chlorine or Methane in pump stations and confined spaces.
