Switching input/output module is a module which can collect and control the digital switching value. It is connected with the wireless data transmission radio through the RS232 interface and the communication protocol is Modbus protocol. The switching input and output module can collect two digital switching states and output two dry contacts at the same time. And it is transmitted through wireless digital radio for remote control.
It is connected with the wireless digital transmission radio through RS232.
Modbus protocol is adopted as the communication protocol.
Wide supply voltage input (DC9 ~ 36V).
