The RH-2-V-S 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 space mounting configuration.
The RH2VS transmitter has a ±2% 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 0 to 5 volt transmitters provide a linear proportional output at terminal O with 0 volts equivalent to 0% RH and 5 volts to 100% RH.
The voltage output transmitters can be wired as a three wire transmitter or as a four wire transmitter to eliminate the effects of wire length. The output voltage is with respect to Terminals N (power supply return) and/or G (signal ground) which are common at the transmitter.
The RH-2-V-S 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.
