2-Wire CO Gas Sensor Module

The 4501-04, 2-Wire Carbon Monoxide Gas Sensor Module eliminates the need for separate power runs and associated power distribution and circuit protection for each device. The 2-wire CO Gas Sensor provides features not found in similar products including: Low maintenance costs due to 180 day (six-month) calibration interval; low installation costs due to 4-20 mA 2-wire loop-powered design; user-friendly operator interface with integral scrolling menu-driven LCD display for easy access to gas status, calibration instructions, adjustment of ranges, and outputs and diagnostic information; non-intrusive calibration to enable calibration without declassifying the area; and common signal output of 4-20 mA.
