RH-D - Duct Mount RH & T Sensor

RH-D are sensors for detecting temperature and humidity. An important feature of this sensor is that, in 3-wire mode, it automatically detects the controller input setting, 4-20mA or 0-10Vdc. This eliminates the need for output jumpers that can be inadvertently set incorrectly. 2-wire power supply selectable via DIP switch. It also provides an on-board LED indication for power status and troubleshooting.
