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

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

The DRV-10 digital timer relay is a universal device for time-controlled control of electrical equipment. It allows setting the on-delay or off-delay in the range of 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 bright digital display, LED status indication and a universal 230 V AC/DC or 24 V AC/VDC power supply. Its slim design takes up minimal rack space.

Functions and features

Digital display
Allows you to easily set and check the countdown. It shows the time in seconds or minutes depending on the selected mode.

Two modes - On Delay and Off Delay
The relay can be used to delay the switching on or off of a device based on a control signal.

Switching via TR input
The 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 (A1-A2 terminals)
- 24 V AC/VDC (A2-A3 terminals)

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

Description of operation

ON Delay - delayed power 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 NO contact of the relay is activated.

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

• The display shows the countdown until power on.

Power-off delay

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

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

• The display shows the countdown until the release.
