HF-TRCK temperature and humidity controller device

HF-TRCK temperature and humidity controller device is mainly used in all kinds of scenarios that need to control the operation of equipment by monitoring temperature and humidity.

The device has 3-channel normally-open control relays, and optional RS485 output of different levels, and adopts MODBUS industrial control bus protocol, which allows multiple modules to access to the bus at the same time for networking. 

● It uses the high-performance and classic SCM of ST company in America, and uses RT_ Thread operating system to control multithreading.

● It uses high performance temperature and humidity measuring chip, which can measure the ambient temperature and humidity accurately and quickly.

● It adopts optional RS485 signal transmission mode and MODBUS industrial control bus protocol, which has reliable performance and good compatibility.

● The device allows the setting of a variety of parameters, making the use more flexible and convenient, and is equipped with a password management system.

● It adopts PID algorithm, which can control the opening and closing of the normally open contacts of the relay in a sensitive and reliable manner.

● The device is characterized by small volume, convenient installation and small space occupation. 

● The use of this product requires a certain basis of MODBUS protocol.

 ● The contact capacity of the exit relay is AC250V/5A and DC30V/5A.

● During the wiring of the 485 communication interface, the armored shielded twisted pair shall be used to ensure the stability of communication.
