3. Product Overview

The 05704-A-0145 is a rack-mounted four-channel 4–20mA gas control card for Honeywell Sieger System 57 fire and gas safety systems. It receives standard analog current signals from toxic gas, oxygen, IR combustible gas transmitters and other 4-20mA field detectors. Each channel supports independent alarm thresholds and continuous loop fault monitoring to identify broken cables or transmitter failures. The front LCD and channel LEDs display real-time gas concentration and alarm status. It works with the matching 05704-A-0121 quad relay interface card to drive alarm beacons, sounders and safety shutdown interlocks. This card is widely used for hazardous gas monitoring in oil & gas, chemical, refinery and offshore facilities.
