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

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

The DRV-10 digital timer relay is a versatile device for timed control of electrical equipment. It allows setting an ON delay or OFF delay in a range 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, an LED status indicator, and a universal 230 V AC/DC or 24 V AC/DC power supply. Its narrow design means it takes up minimal space in the cabinet.

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 to delay the switching ON or OFF of a device based on a control signal.

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

LED Indication
Two LED indicators show the status of the power supply and the relay coil.

Universal Power Supply
- 230 V AC/DC (terminals A1-A2)
- 24 V AC/DC (terminals A2-A3).

Easy Installation on DIN Rail
The compact design (23 mm wide) allows installation even in small cabinets. IP20 protection.

• delayed contactor switching

• time control processes in household and industry

When a signal is applied, the timed control is activated according to the selected mode. The display shows the countdown time.

Operation Description

ON Delay - Delayed ON

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

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

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

• The display shows the countdown time until switching ON.

OFF Delay

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

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

• The display shows the countdown time until switching OFF.
