Part number: A-1255
In Stock : Available

ATC remote Wi-Fi I/O Modbus module, support RTU/ASCII/TCP protocol, through the RS-485 communication port and ATC series controller to control the communication. And it also can communicate with other devices that support the Modbus RTU/ASCII protocol, host computer communication or remote command control. It also can be connected to the A-3290 Wi-Fi bidirectional remote controller directly control the output, no the need for any controller. The Wi-Fi function of the module support set up AP mode and Client mode to make the series of module work in Bus network or networking by Wi-Fi. To make the I/O points can flexible expansion.
