Transmitter is equipped with three binary inputs for detection of two-state events - e.g. water, smoke, glass break detection, door contact. Transmitter is equipped with internal terminals for powering of connected external detectors.

Measured temperature and relative humidity is recalculated to other humidity interpretations - dew point temperature, absolute humidity, specific humidity, mixing ratio or specific enthalpy.Reading and pressure output available in these units: hPa, kPa, mbar, mmHg, inHg, inH2O, PSI, oz/in2. Degrees Celsius and Fahrenheit are user selectable.

State-of-the-art capacitive polymer sensor ensures excellent calibration long term stability.Transmitter is equipped with two relay outputs for alarm indication or control of external devices. Each relay can be assigned to any measured or computed value. For each relay setting of delay, hysteresis, audible alarm is enabled.
