Electronic Timer Relays

Switching, controlling, visualizing - electronic timer relays

The product range offers timer relays with multi functions and adjustable time ranges but also relays with special functions like delay on make, delay on break, circuit closing wiping, flashing, clock generator and star-delta relays.

Delay on Make
On application of power the selected delay time tv starts and at its end the output relay pulls on. It only drops off when power is removed. If power is interrupted during the delay time run, the delay time starts anew after application of power and the recovery time cycle tw.

Circuit closing wiping
On application of power the output relay pulls on without delay and drops off after the wipe time cycle tv. Power has to be applied at least for the wipe time period. If it is interrupted before the end of the wipe time the relay immediately drops off. This operation is only repeated when power is again applied and the recovery time tw is over.

Delay on Break
Power needs to be applied continuously. The output relay pulls on without delay when the potential free control contact is closed. After opening of the control contact the selected delay time tv starts, at its end the relay drops off.

Circuit opening wiping
Power needs to be applied without interruption. After closing of the potential free control contact the output relay stays in stored position. The selected wipe time only starts when the control contact opens. The relay drops off at the end of the wipe time. This operation is only repeated when power is turned on again and the recovery time tw is over.

Flashing, interval start
On application of power the output relay stays in stored position for the selected interval time cycle tp and then pulls on for the pulse time ti. This operation is repeated until power is removed.

Flashing pulse start
On application of power the output relay pulls on for the selected pulse time ti and then drops out for the interval time tp. This operation is repeated until power is removed.
