Description
Accu-Time is truly a Universal Time Delay Relay. All the programming and adjustments are located on the top face of the control. Programming of the desired time range and mode of operation are accomplished via four ON/OFF switches. The actual time delay is set by means of a three digit, direct reading, thumb wheel switch. The circuit comprised of a fixed oscillator and CMOS digital counting circuit. The electromechanical relay output is rated at a full 10 amperes.
