The RH110, 210 and 310 series of transducers are specifically designed for use in applications where both a temperature and RH signal are required. Each product includes an RH transmitter similar to the RH100, 200 or 300 and also a RTD temperature transmitter conveniently designed onto one PCB to ensure the highest accuracy and reliability available.

The RH110 Wall Mount comes standard in the Designer Space enclosure designed for ease of installation and is available as a 24 VDC loop powered device with both temperature and RH signal outputs. The RH210 Duct Mount features a 9" stainless steel probe with integral 60 micron filter, operates on 24 VAC/DC and is available with either voltage or loop powered current output signals for both temperature and RH. The RH310 OSA transducer is mounted in a compact 4" x 4" weatherproof enclosure with integral sun shield and potted sensor assembly. It also operates on 24 VAC/DC with both current and voltage outputs available and includes industrial electronics rated for use from -40C-85C (-40F-185F).

These devices feature the same humidity specifications as the RH100, 200 and 300 products, except the output signal types are specified when ordering (not jumper selectable) and note that the RH110 is only available as a DC loop powered device.

The temperature transmitter specification are also the same as those listed for the RH10, 200, and 300 products except the RH110 is only a DC loop powered device. For all devices, the RH and temperature signals are completely independent from each other.
