Product Description

The 05701-A-0327 control card is a plug-in module used within the Honeywell Analytics Series 57 rack system. Each card is capable of processing signals from up to four independent gas sensors. It acts as the “intelligence” of the system, converting sensor signals into readable data, managing alarm thresholds, and triggering safety relays or visual indicators when gas concentrations exceed pre-set limits.

Product Parameters

• Channels: 4 independent channels per card.

• Input Signal: Typically 4 to 20 mA (supports various gas bridge inputs or pellistor sensors depending on configuration).

• Power Consumption: Approximately 4.5 W (varies based on sensor types connected).

• Alarm Levels: 3 programmable alarm levels per channel (Low, High, and Fault).

• Display: Integrated 4-digit LCD per channel and LED status indicators (A1, A2, A3, and Fault).

• Output: * Individual channel relays.

  • Common alarm relays via the rack backplane.

  • Optional 4 to 20 mA analog output for remote monitoring.

• Operating Temperature: $0^\circ\text{C}$ to $55^\circ\text{C}$.

Product Advantages

• High Density: By supporting four channels on a single card, it significantly reduces the rack space required for large-scale gas detection installations.

• Individual Channel Logic: Each channel is fully independent; a fault or alarm on one channel does not interfere with the monitoring capabilities of the other three.

• User-Friendly Interface: The card features a clear LCD and tactile buttons for easy “at-the-rack” configuration and calibration.

• Reliability: Part of the proven Series 57 family, known for its long-term stability and rugged performance in industrial safety environments.

• Flexible Configuration: Supports a wide variety of gas sensors, allowing for a mix of flammable and toxic gas monitoring within the same rack.

Precautions for Use

• Rack Compatibility: Ensure the card is correctly seated in a compatible Series 57 rack and that the backplane wiring matches the channel configuration.

• Calibration: The card must be calibrated in conjunction with the specific field sensors it is monitoring to ensure accurate gas concentration readings.

• Electrostatic Discharge (ESD): As with all sensitive electronics, use ESD protection (wrist straps) when handling the card to prevent damage to the internal circuitry.

• Sensor Selection: Verify that the drive current or voltage set on the card matches the requirements of the connected gas detector head (especially for pellistor/bead type sensors).

Product Applications

• Oil and Gas Refineries: Monitoring for combustible gas leaks in processing areas and storage tank farms.

• Chemical Plants: Detecting toxic gas releases and ensuring oxygen levels are safe for personnel in confined spaces.

• Water Treatment: Monitoring for Chlorine or Hydrogen Sulfide ($H_2S$) levels.

• Power Generation: Detecting hydrogen leaks in turbine cooling systems or methane in fuel lines.

• Manufacturing Facilities: Providing general plant safety monitoring where hazardous gases are used in production.
