3. Product Overview

The 05701-A-0351 is a rack-mounted analogue output interface card for Honeywell Sieger System 57 fire and gas monitoring racks. It is fitted behind the 5701 series gas control cards to provide a scalable 4–20 mA isolated analogue signal proportional to measured gas concentration. This standard analogue signal transmits real-time gas readings to remote DCS, PLC or chart recorders for central plant monitoring. Galvanic isolation suppresses ground loop noise and protects the gas control card from surge damage on the analogue loop. The front LED confirms card active status for quick health checks. It is widely used in oil & gas, chemical and refinery hazardous fire and gas safety systems.
