DRV-10 Digital Timer Relay with ON/OFF Delay, Display, and Control Signal

The DRV-10 digital timer relay is a universal device for timed control of electrical equipment. It allows for setting an ON or OFF delay within a range of up to 99 minutes. The relay is triggered by a control signal on the TR input and is suitable for home, commercial, and industrial applications where precise timing is required.

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

Functions and Features

Digital Display
Allows for 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 for delayed switching on or off of the device based on a control signal.

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

LED Indication
Two LEDs indicate power status and 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.

Application

The relay is suitable for:

• delayed switching of fans (toilet, bathroom), lighting

• motor start control

• delayed switching of contactors

• time-controlled processes in home and industrial applications

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

Operation Description

ON Delay - Delayed Connection

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

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

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

• The display shows the countdown until switching on.

OFF Delay

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

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

• The display shows the countdown until switching off.
