Space Mounted CO and Temperature Sensor
Description
A valuable feature of this sensor is when in 3-wire mode it automatically detects what the controller input is set to, 4-20mA or 0-10Vdc. 2-wire loop powering selectable via DIP switch. The long life electrochemical Carbon Monoxide sensor makes it ideal for many applications including underground parking, loading bays and warehouses.
Features
- Pre-calibrated Electro-Chemical sensing elements
- Auto detection 0-10Vdc or 4-20mA outputs, loop powering via DIP
- Easy installation: 2-part, push-in spring terminal blocks
- Direct thermistor options
