MC Series Microprocessor Timers

MC Series

The MC Series is a range of micro processor based modules which can be used for sophisticated control applications. They are designed to handle complex functions and this makes them an economic substitute for PLC type controls. They are pre-programmed at the factory for the customer’s particular application and can have up to four inputs and multiple outputs up to 60 amps. In addition to PLC applications, the MC may be used for cam timers, coin counters/accumulators, door/gate controls or where multiple timers are required.
