General Information

• Brand: Honeywell
• Model: 05701-A-0361
• Product Type: Engineering Card (part of the Honeywell 5701 series)
• Application: Gas detection systems, process control, and industrial automation.
• Function: Provides a user interface for commissioning, diagnostics, and real-time monitoring of System 57 control cards. Integrates with backplane communication to manage sensor inputs, alarm outputs, and system parameters.

Technical Specifications

Key Features

1. System Configuration & Maintenance:
   • Centralized interface for programming and adjusting parameters of System 57 control cards (e.g., alarm setpoints, sensor calibration).
   • Real-time clock for timestamping calibration records, event logs, and alarm history.
2. Diagnostics & Fault Management:
   • Self-validation of circuit components, software, and backplane communication to ensure system integrity.
   • LED indicators for power status, communication activity, and fault conditions.
3. Security & Access Control:
   • Lockable "Engineering Key" feature to restrict unauthorized configuration changes.
   • Password-protected access to critical functions (e.g., alarm reset, system shutdown).
4. Flexible Integration:
   • Direct compatibility with Honeywell System 57 racks and modules (e.g., gas detection controllers, relay cards).
   • Supports Modbus RTU communication for integration with external SCADA or PLC systems (optional on some variants).

Applications

• Gas Detection Systems:
  • Monitors and controls up to 16 gas sensors (e.g., combustible, toxic, or refrigerant gases) in industrial settings like oil refineries, chemical plants, and power stations.
  • Triggers alarms, ventilation systems, or emergency shutdowns based on predefined thresholds.
• Process Control:
  • Manages sensor inputs and relay outputs for machinery interlocks, process optimization, and environmental monitoring.
• Safety Compliance:
  • Ensures adherence to international standards (e.g., IEC 61508 for functional safety) in hazardous zones (Class I, Div 2, Zone 2).

Documentation

• User Manuals: Available through Honeywell’s official support portal, detailing wiring diagrams, configuration workflows, and troubleshooting for System 57 integration.
• Datasheets: Provide technical specifications, pinouts, and compliance certifications for specific model variants.

Notes

• Model Variants:
  • Some sources mention optional features like additional communication protocols (e.g., RS485, CAN) or expanded I/O capabilities, which may vary by region or application.
  • Dimensions and weight discrepancies (e.g., 70 mm × 40 mm × 30 mm vs. 170 mm × 25 mm × 132 mm) likely reflect different housing designs or accessory configurations.
• Power Supply Clarification:
  • While the card operates on 18–32 V DC, it relies on the System 57 rack’s power bus for stable voltage distribution. Redundant power supply options are available for mission-critical applications.
• Third-Party Information:
  • Specifications are compiled from third-party sources and Honeywell partner documentation. For definitive technical details, consult Honeywell’s official literature or contact their technical support.
