The Model 301 Programmable Timer is designed to replace over 100 standard timers. One Model 301 can be set for one of five functions, covers four timing ranges, and has a universal power supply for any AC voltage from 24 to 240 volts, or DC voltage from 12 to 240 volts.

The digital design of the Model 301 provides high accuracy, repeatability and response time. The output of the Model 301 is a heavy-duty DPDT electromechanical output relay.

Programming options are chosen by simply setting the four DIP switches on the top of the relay, and then adjusting a potentiometer for percent of delay. An LED indicator illuminates when the relay is energized.
