PT447-11

Changeover timer relay with idle time

It is used in automations that require a cyclic ON-OFF-ON type process, with independently adjustable times for ON and OFF operation.
SKU: PT447-11 Κατηγορία:
It is used in automations that require a cyclic ON-OFF-ON type process, with independently adjustable times for ON and OFF operation. The process starts with the application of the supply voltage, by arming Relay 1 for an adjustable time T2. This is followed by an adjustable pause time T1 where both Relays are off. It then arms Relay 2 which again remains armed for an adjustable time T2. The above process is repeated continuously for as long as the device is supplied with voltage. The times T1 and T2 are selected when ordering and can be from 1 second to several hours. It is digital and works with a microcontroller. The product is available with an operating voltage of 24VAC/DC upon request.
