# A/RH1-R-ACI-Automation Components-Humidity Sensors

**Manufacturer:** ACI-Automation Components  
**MPN:** `A/RH1-R`

The ACI A/RH1-R : Wall Relative Humidity (RH) Sensor utilizes a capacitive sensing element to deliver a proportional analog output. It features on board dip switches for selecting the desired output signal and can be powered by AC or DC power sources. Field calibration is possible through the on board increment and decrement dip switches, providing increased flexibility and long-term performance.
