Honeywell 05701-A-0301 System 57 Control Cards

The Honeywell 05701-A-0301 is a single-channel control card designed for Honeywell System 57 / 5701 gas detection and analytics platforms. It performs real-time signal conditioning, alarm processing, and control logic execution for an individual sensor channel. The card accepts dedicated sensor inputs—including high-temperature sensing elements rated up to 1000 deg C—and converts them into standard 4-20 mA analog output signals for system monitoring and safety interlocks.

Sensor Interface and Output Conditioning

The module conditions input signals from connected sensors and processes them through internal threshold logic to drive alarm states. Operating as a single-channel control node, the 05701-A-0301 provides an isolated 4-20 mA analog output representation of the measured variable, allowing direct integration into centralized control networks and distributed data acquisition panels.

Environmental and Enclosure Specifications

Constructed for demanding industrial environments, the module features an IP67 rating and NEMA 4X compliance for protection against dust, water ingress, and corrosive conditions. The card operates over an extended ambient temperature range of -40 deg C to +85 deg C, with physical dimensions of 170 mm x 25 mm x 112 mm and a weight of 0.165 kg.
