Characteristics of the monitoring device
(1) Working environment: temperature: -25~65℃; humidity: ≤95%RH(25℃)
2)Using the CPU of ARM architecture, the data processing ability is strong and the system is stable.
(3) LCD liquid crystal interface, digital and Chinese display, key operation.
(4) The internal circuit board design concept is modular design, strong and weak power separation, to avoid space crosstalk.
5) Clock chip included: with time scale historical data storage.
(6) RS485 communication function: international open standard protocol Modbus-RTU.
