Mitsubishi Alpha

The ALPHA has been designed to fill the void between such items as timers, relay modules that can handle simple tasks, and PLCs which are capable of handling complex operations. In many applications relating to security, building management or low level automation, such a device is required. In these circumstances all that is needed is a supervisory device which is adaptable and flexible to handle a wide range of tasks; the ALPHA has been designed to fulfil these needs. The programming of Alpha has been designed to be simple, without the need to have an in depth knowledge of equipment programming, and to make it easy to use.
