The CT02 timer is designed for time sequence control of electrical actuators. The time setting adjustment is done by rotating a dial on the front panel The timing is started at power-on or by external ‘start/stop’ contact. Various modes of operation – on-delay, off-delay, pulse output, and cyclical output – are available. The operating modes as well as the time range (for variant ‘S’) can be selected via micro switches. The timer may be equipped with up to 2 relays – main timing relay and auxiliary relay, which is activated at power-on or simultaneously with the main relay. CT02 has no indication, is very easy to set and operate. It combines simplicity and low cost, while possessing and
has all the main functions of a modern electronic timer.
