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

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

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

The relay has a clear digital display, LED status indicator, and universal power supply 230 V AC/DC or 24 V AC/VDC. Its narrow design takes up minimal space in the cabinet.

Functions and features

Digital display
Allows easy setting and monitoring of the countdown. Displays time in seconds or minutes, depending on the selected mode.

Two operating modes - delayed switching on and delayed switching off
The relay can be used for delayed switching on or delayed switching off of a device based on a control signal.

Switching via TR input
Time functions are activated by the rising edge of the signal at the TR (TRG) input.

LED indication
Two LEDs indicate power status and relay coil status.

Operating description

ON Delay - delayed switching on

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

• After the elapsed time, the NO contact of the relay switches on.

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

• The display shows a countdown to turn on.

Off delay

• The relay switches on immediately after the rising edge of the signal.

• The relay remains on for the duration set by the timer.

• The display shows a countdown to shutdown.
