Timer / Time Delay On/Off Relay / One Shot Relay

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

The digital timer relay DRV-10 is a universal device for time control of electrical equipment. It allows setting switch-on or switch-off delay 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 requiring precise time measurement.

The relay has a clear digital display, LED status indicator, and universal 230 V AC/DC or 24 V AC/VDC power supply. Thanks to its narrow design, it takes up minimal space on the shelf.

Functions and features

Digital display
Allows easy setup and counter monitoring. Displays time in seconds or minutes depending on the selected mode.

Two operating modes - switch-on delay and switch-off delay
The relay allows delaying device switch-on or switch-off based on the control signal.

Switching via TR input
Timing functions activate on the rising edge of the signal at the TR (TRG) input.

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

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

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

Application

The relay is suitable for:

• For delayed switching of fans (toilet, bathroom) and lighting.

• For motor start control

• Delayed switching of contactors

• Time-controlled processes in households and industrial applications

When the signal is applied, timing activates according to the selected mode. The countdown is visible on the screen.

Operation description

ON Delay - delayed switch-on

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

• After the time elapses, the relay NO contact switches on.

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

• The screen displays a countdown until switch-on.

Shutdown delay

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

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

• The screen displays a countdown until shutdown.
