RH RESISTIVE
RH with Resistive Temperature Output
The A/RH Series relative humidity transmitters (with resistive temperature output) utilize a capacitive
sensing element to deliver a proportional analog output. This series features on board DIP switches which
allow the user to select the desired output signal. In addition, 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. Duct and Outside Air configurations feature conformally coated
circuit boards for moisture resistance. Several RTD and thermistor temperature sensing elements are
available in this series.

ORDERING
Select one Series (A). If A/RH1 is selected, you must specify a 20% range. Choose a Temperature Sensor (B), one Configuration (C), & one RH
Output (D). When selecting your Configuration (A), if “R2S”, “RS”, “RSO” or “R2SO,” please choose a Pot Value (E), a Sticker (F) & a Pot Action
(G). If ”R2S”, “RS”, “RSO” or ”R2SO” is not selected, your Part Number is finished after completing RH Output (D). NOTE:
not available for the SP configuration.
