3. Product Overview

The 0571-A-0325 is a rack-mounted DC power distribution card for Honeywell Sieger System 57 fire and gas monitoring racks. It accepts 24 VDC main power and supplies filtered, stable power to the rack backplane for all gas control, relay and interface cards. The auxiliary terminal supports backup battery connection to maintain continuous operation during main power loss. Integrated fuse protection limits fault propagation and avoids full rack shutdown. The separable terminal block enables card replacement without disconnecting field wiring. It is used in hazardous gas safety systems for oil & gas, chemical and refinery plants.
