Description
Temperature, humidity, and atmospheric pressure converters H7430 with RS485 outputs. Equipped with two relay outputs for signaling, indication, or control of external devices, discrete inputs. For each relay, delay settings, hysteresis, and sound signal are included. Parameters are easily configured using a computer or the keyboard on the front panel of the sensor. The converter is controlled by a microprocessor housed in a durable plastic case with terminal connections. A large two-line LCD display is designed for simultaneous display of 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 the quality of the indoor climate. 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.
