GX20/GP20 (/CM2 option)GM (/CM2 and /CS2 options)920MHz Wireless Communication

OVERVIEWWireless communication (902.1 to 927.9MHz band) enables the GX20(/CM2), GP20(/CM2), GM10(/CM2) to communicate as a master with compatible GM10 slaves (/CS2), UT52A/UT32A(suffix code type 3:B), and Wireless Input Unit (GX70SM), other Modbus devices and wireless communication sensors. Because slaves are equipped with a repeater function, they can be used to extend the communication distance.(This product can only be used in the US.)

Even when wireless communication is cut off, the most suitable communication route is automatically selected.
