The time relay is manufactured under the most modern methods of qualitative and reliable materials.
The timer is adjusted for DIN-rail mounting. It is used to provide reliable and safe time hold at “star/delta” starters and it is used for setting fixed time intervals. Programming is done through selection of the time unit (seconds or minutes) and rate (x 0.1 or x1) by the slide switches, and then selection of a value from the timer knob (from 0 to 10). Whenever timer circuit receives a signal, it executes the set cycle and then stops until a new signal is available.
It gives possibility for time adjustment for motor unwinding in star up to 600s and time change to delta according to the consumer’s need.
