The RH-5-I-O/A Relative Humidity (RH) and Temperature transmitter is designed for continuous monitoring of relative humidity (RH). It provides accurate and reliable measurement for building automation and environmental control systems. The units feature very low profile sensor enclosures that are virtually unnoticeable in most installations. It also has an outside air mounting configuration.

The RH5IO/A transmitter has a ±5% RH accuracy (20% to 95% RH). For monitoring and controlling in critical environments, the units can be precision calibrated to 1% accuracy within a specified RH range.

The 4-20 mA transmitter will provide a linear proportional signal with 4 mA corresponding to 0% RH and 20 mA to 100% RH. These are loop powered devices; therefore, only two wires are required.

The RH-5-I-O/A transmitter provides a linear output of 4-20 mA corresponding to 0 to 100%RH. The RHT transmitter also provides a 4-20 mA signal corresponding to any of the selected standard temperature ranges specified.

The RH-5-I-O/A includes a temperature option that is a separate circuit board but mounted in the same housing along with the relative humidity transmitter. The temperature transmitters are entirely separate circuits from the RH transmitters. Transmitters are loop powered devices. Therefore, only two wires are required. One wire may be common with the RH transmitter.
