EH Series Humidity Sensors - Installation Instructions

The EHx duct and outdoor transmitters are RH transmitters that can be powered with either an AC or DC supply voltage. The transmitters can also include an optional sensor for monitoring temperature. All units are shipped from the factory set up with a 4-20 mA output. The transmitters are field selectable with a 4-20 mA, 0-5 VDC, or 0-10 VDC output signal that is equivalent to 0 to 100% RH.
