1 . Real time clock anti loss precision circuit design

Using the precision technology of the built-in lithium battery clock module, the clock information is not lost even if the short circuit, it can work for 20 years even without charge, the clock accuracy is high, don’t need frequent calibration


2 . Three-level lightning protection and anti surge circuit design (breakthrough overvoltage protection)

Using high three-level lightning protection design, it can be hit 50 times by 5000v induction thunder ,but it will not be damaged, the anti surge circuit function are also in the higher grades.


3 . Jumper-free adaptive fault and automatic isolation intelligent communication circuit


RS485 communication mode,can be jumper-free selection, plug and play, easy to operate, not easy to make mistakes . If a controller failure, the controller automatically isolates itself from the communication bus, it will not affect the other controllers and the communications , It is also convenient for engineers to find faults quickily in the large systems.
