SMI200 Programmable compact controller

SKU: smi200
The SMI200 is a programmable compact controller for monitoring and control industrial processes. Instead of a number of inputs and outputs, the device is equipped with an RS485 interface. Due to this solution, the SMI200's enclosure is significantly minimized and fits into a standard 22.5 mm borehole for signal lamps, which provides quick and easy installation plus plenty of SMI200s can be accommodated in a control cabinet door or on a panel. Over the RS485 interface, any Modbus extension modules (e.g., our Mx110 Series) can be connected to the device. As a result, any required combination of I/O-points can be selected. In a Modbus network, the SMI200 can operate both as a Master and as a Slave. The device programming is carried out using akYtec ALP programming software over micro-USB.
