Timer / Time delay on/off relay / One Shot relay

Digital timer relay DRV-10 with ON/OFF delay, display, and control signal

The DRV-10 digital timer relay is a universal device for time-controlled operation of electrical equipment. You can set a ON Delay or OFF Delay up to 99 minutes. The relay is activated by a control signal at the TR input and is suitable for household, commercial, and industrial applications where precise timing is required.

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

Functions and features

Digital display
This allows the countdown to be easily set and monitored. Displays time in seconds or minutes, depending on the selected mode.

Two operating modes - ON Delay and OFF Delay
The relay can be used to delay turning the device ON or OFF based on a control signal.

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

LED indication
Two LEDs indicate the status of the power supply and the status of the relay coil.

Universal power supply
- 230 V AC/DC (terminals A1-A2)
- 24 V AC/VDC (terminals A2-A3)

Easy mounting on DIN rail
Compact design (23 mm wide) allows installation even in small cabinets. IP20 protection.

• delayed switching of contactors

• time-controlled processes in household and industrial applications

When a signal is applied, the timing is activated according to the selected mode. The countdown is visible on the display.

Description of operation

ON Delay - delayed activation

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

• After the time has elapsed, the NO contact of the relay is activated.

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

• The display shows the countdown to activation.

OFF Delay

• After the rising edge of the signal, the relay is immediately activated.

• The relay remains activated for the time set by the timer.

• The display shows the countdown to shutdown.
