USER-FRIENDLY MEASURING DEVICES humidity transmitters rht-mod series Wall mount humidity transmitters for building automation systems that use Modbus serial communication protocol RHT-MOD relative humidity transmitters are engineered for building automation systems in the HVAC/R industry. The RHT-MOD measures relative humidity (rH), and temperature (T). RHT-MOD devices are available with large touchscreen display making configuration of the device quick and easy. RHT-MOD series devices include: • Separate field configurable Modbus output for each measurement parameter (rH and T) • One analog output for selected measurement: voltage (0/2-10 V) and current (4-20 mA) • Optional relay output RHT-MOD series devices are commonly used to monitor: • humidity and temperature levels in offices, public spaces, hospitals, meeting rooms and classrooms • humidity and temperature in various commercial applications • humidity and temperature in HVAC/R environment Copyright HK Instruments 2017 www.hkinstruments.fi Datasheet Version 6.0 2017
