HONEYWELL 05701-A-0302 Analytics Single Channel Control Card

Description

The HONEYWELL 05701-A-0302 is a single channel control card belonging to the System 57 series, engineered specifically for industrial gas detection and fire alarm systems. As a dedicated single channel control unit, it supports full control of one gas sensor or fire detector, providing precise signal collection and processing capabilities to ensure accurate monitoring of target parameters. Key features include multi-level alarm settings (A1, A2, A3) with fault detection, plus integrated signal isolation that separates input/output signals from system power to enhance operational stability. It is compatible with 5701, 5704, and 5704F control systems, and integrates seamlessly with other cards in the System 57 rack via the backplane connection.

The card features a four-part LCD display with a 25-segment analog readout, 4-character digital display, 4-character information display, and a boot/card selection icon section. It also includes LEDs for A1, A2, A3 gas alarms, fault, and status indicators, along with an alarm reset/card selection button, and offers 1% full-scale deflection (fsd) step resolution for alarm set points. Technical specifications include an 18V to 32V DC power supply, typical power consumption of 3.75W for catalytic setups (including sensor) and 3.25W for 4-20mA configurations, electronic drift of less than 2% per 6 months, dimensions of 17cm x 2.5cm x 11.2cm, and a weight of 0.165kg. Designed for indoor, non-hazardous areas, it requires regular calibration and maintenance, and is suitable for use in industrial gas detection, fire alarm, environmental monitoring, and process control safety systems.
