More about the product

The human-machine interface needs to communicate data with the main control board, PLC, host computer, etc. There are many types of communication interfaces such as RS422 and RS485, and the human-machine interface has different types such as standard operation panel and embedded human-machine interface.

The main function of the communication interface board is to configure these different interfaces. Various interfaces inside and outside the inverter are connected to the communication interface board, and then connected to the human-machine interface through the communication interface board, thereby simplifying the external communication connection of the human-machine interface.
