The model R7E Remote I/O module is a new addition to M-System’s varieties of R7 Series Compact Remote I/O. The module has the power supply, network and I/O sections all in one piece. It provides an ideal solution for wiring saving system using Modbus/TCP protocols over Ethernet, efficiently transmitting a small number of I/O signals scattered around remote locations to a PLC and a graphic operator panel.
