If you"re looking for an easy way to control the temperature of anything from a circuit, a heatsink, to a room, this little thermostat control module will do the trick! A built-in NTS temperature sensor is included, and can either be board mounted or remotely connected via the built-in terminal strip. The temperature range is 41F to 86F. Once adjusted to the desired temperature a built-in relay provides the control circuit. In addition a bright red LED indicates the state of the thermostat. The module runs on 12VDC at 100mA. The control relay is rated at 24V at 3A making it easy to interface with any of your circuits. The board measures 2.1" x 2.4" x 1.1". Temperature control is normally a hassle, use this little module and make it a breeze!
