SC807 is a high-performance 2-wire Relative Humidity and Temperature (RH+T) Transmitter. Its relative humidity and temperature transmitter is available in surface mount, duct mount and remote sensor versions. Remote external sensors, SHT20, SHT30 (wall-mount) and SHT40 (duct-mount) may be placed as far as 25 meters from the unit. This transmitter is accurate to 3% for relative humidity and within 0.5 °C for temperature. SC807 transmits two isolated output signals to other devices such as a Programmable Logic Controller (PLC) or Solid-State Relay (SSR). Signal isolation protects your devices and machines downstream of our instruments from damaging fluctuations in the input signal. SC807’s microcontroller technology linearizes the input which makes control more effective. It is powered by a 4.5 - 32 V DC loop supply and has a loop drop of no more than 4.5V, which is remarkably low amongst such products. The RH+T transmitter is user programmable by a PC, connected via PCC82, a PC configurator by Radix.
