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

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

The DRV-10 digital time relay is a universal device for time-controlled control of electrical equipment. It allows you to set ON Delay or OFF Delay in a range of up to 99 minutes. The relay is triggered by a control signal on 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 universal 230 V AC/DC or 24 V AC/VDC power supply. Thanks to its narrow design, it takes up only a minimum of space in the rack.

Functions and features

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

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

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

LED indication
Two LEDs show 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
Compact design (23 mm wide) allows placement even in small cabinets. IP20 protection.

• delayed switching of contactors

• Time controlled processes in domestic and industrial applications

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

Description of operation

ON Delay - delayed switching 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 will turn on.

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

• The display shows the countdown to power-up.

OFF Delay

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

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

• The display shows the countdown to trip.
