Description
The converter is equipped with two relay outputs for signaling, indication, or control of external devices. It also has three discrete inputs for connecting external devices such as smoke detectors, motion sensors, etc. Delay settings, hysteresis, and sound signal are enabled for each relay. It is installed in a 19” 1U rack. Parameters are easily configured using a computer or the keyboard on the sensor's front panel. The converter is controlled by a microprocessor housed in a durable plastic case with terminal connectors. A large two-line LCD display is designed to simultaneously show two parameters. The display can be turned off if necessary.
Recently, temperature and humidity levels have been considered as the most important parameters responsible for indoor climate quality. Especially in buildings and rooms with large gatherings of people, such as conference halls, hospitals, schools, cinemas, theaters, and wellness centers.
With the help of such sensors, engineers, environmental experts, and healthcare specialists can optimize ventilation to create a comfortable and "Healthy" indoor climate.
ATTENTION, the device is currently discontinued.
