Timer / on/off delay relay / one-shot relay

Digital time relay DRV-10 with turn-on/turn-off delay, display, and control signal

The digital time relay DRV-10 is a universal device for controlling electrical equipment with time control. It allows you to set a turn-on delay or turn-off delay within a range of up to 99 minutes. The relay is triggered by a control signal at the TR input and is suitable for home, commercial, and industrial applications where precise timing is required.

The relay features a clear digital display, LED status indication, and universal power supply 230 V AC/DC or 24 V AC/VDC. Thanks to its narrow design, it occupies minimal space in the cabinet.

Operation description

Turn-on delay - delayed start

• After the rising edge of the signal at the TR input, the countdown of the set time begins.

• After the time expires, the NO contact of the relay will close.

• The relay remains on until the next rising edge of the signal at the TRG input.

• The display shows the countdown to power-on.

Turn-off delay

• After the rising edge of the signal, the relay switches on immediately.

• The relay remains in the ON state for the time set by the timer.

• The display shows the countdown to shutdown.
