We stock Mitsubishi Alpha and Mitsubishi Alpha 2. These are two very basic compact PLC systems that are available with different numbers of I/O. The PLCs are available with relay outputs or transistor outputs and with 24 VDC and 230 VAC power supply. Some inputs can handle analog signals and the Alpha 2 can be expanded with analog outputs. We can offer used/refurbished Mitsubishi Alpha and Mitsubishi Alpha 2 spare parts from our stock.
