Timer / On/Off time delay relay / One-shot relay

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

The digital time relay DRV-10 is a universal device for time control of electrical equipment. It allows you to set an activation or deactivation 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 domestic, 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 its narrow design, it occupies minimal space on the panel.

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

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

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

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

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

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

Operating description

ON Delay - delayed ON

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

• After the time has elapsed, the relay's NO contact closes.

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

• The screen shows the countdown for the ON.

Off delay

• After the signal rises, the relay switches on immediately.

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

• The display shows the countdown for the trigger.
