A/RH5-D - The A/RH Series Relative Humidity Duct Transmitters utilize a capacitive sensing element to deliver a proportional analog output. This series features onboard DIP switches which allow the user to select the desired output signal and can be powered by AC or DC power sources. Field calibration can be performed by using the on board increment and decrement DIP switches. These enhancements provide increased flexibility and outstanding long-term performance. The A/RH Series is covered by ACI's Five (5) Year Limited Warranty. Single point field calibration Field selectable output signals (0-5 VD 0-10 VD 4-20 mA)
