Make everything easy in the process of use!


1.Easy to install
* Key hole design
* Guide rail installation 
* Spring-snap control terminal, no screwdriver required.

2.Convenient application
* Change the control module arbitrarily
* Can expand multifunctional I/O module, PG card and bus module at will
* Add software application macros for easy debugging
* Parameter copy function.

3.Simple after-sales repair
(1) It can be replaced damaged unit, such as OP panel, CM control module, 
PM power module, PG expansion module, fan;
(2) When the PM is damaged, there is no need to replace the CM, which is 
convenient to replace without adjusting the parameters and control lines,
