Remote Expansion Unit (RE-1 & RE-2) is an external Modbus slave devices to expand the I/O points of Remote Terminal Unit (RTU). With its Modbus interfaces capability, wide ranging devices from simple digital I/O, various types of analogs, energy meters and so on can be monitored and controlled. The management of the RTU is through web-access. Web access can be achieved using the network cable connecting to the device RJ-45 port or using GPRS connection. This controller is ideal for a local network environment as well as in unmanned remote locations.
