Overview:

The product adopts a digital temperature and humidity sensor, which displays temperature and humidity values in the form of a digital tube. It is equipped with fan and heater contacts, and has functions such as load disconnection alarm, sensor fault indication, RS485 communication, etc. Suitable for unmanned substations. Users can program the upper and lower limits of temperature and humidity, cycle display mode, communication parameters, etc. through buttons. This series of products has strong anti-interference ability and high reliability, and complies with GB/T 15309-1994 and GB/T 13978-92.

Main features of the second product:

Adopting integrated digital temperature and humidity sensors with high measurement accuracy;

Each measurement corresponds to 2 control output contacts, which can be connected to a heater and a fan respectively;

Through button programming, users can freely set control parameters and controller operating parameters;

Instrument setting data * saved, not lost after power failure;

Extremely strong ability to resist electromagnetic interference;

It has password protection function.

Three technical indicators

Switch setting, hysteresis to control output:

In the process of temperature and humidity control, the difference between the temperature or humidity value when the executing component (heater or fan) starts working and the temperature or humidity value when it stops working is called hysteresis.
