The compact-sized DERELL DEZ 37 R A model time relays belong to the basic time relay series and are widely used in industrial machine environments. It features a next-generation CPU and comes in a 36x72 mm body. The input supply is AC/DC 220V and it uses a 3-digit 7-segment display. There are 2 relay outputs. The first relay activates with power-on, while the second activates with a delay or toggles in flasher mode according to the set time.

The device offers two operation modes: DLY mode (delay on pull-in) and FLS mode (flasher). DEZ time relays are designed for the most basic timing applications and provide easy installation and operation.

- This is a time relay, part of the basic time relay series
- Dimensions: 36x72 mm
- Power supply: AC/DC 220V
- Panel cut-out dimensions are available in the product image
- 3-digit 7-segment display is used
- 2 relay outputs available
- First relay is activated with power
- Second relay operates with delay or toggles (loop) in flasher mode
- Device is controlled by next-gen CPU
- Time settings can be up to 999 seconds or 999 minutes (selectable)
- Time unit (seconds/minutes) can be selected via the program
- Operation mode (DLY or FLS) is also configurable via the program
- Time counts downward
- Starts working as soon as power is applied

- DLY mode (delay on pull-in): First relay activates on power-on. Second relay activates after a delay, displaying END message on screen after the countdown.

- FLS mode (flasher): First relay activates on power-on. It toggles on and off with set A (active) and B (pause) times. Highly favored by machine operators.

- If the features above match your application, DEZ model time relays offer an economic and reliable solution.

- If using DLY mode, you need to power cycle the system to restart
- If the power is constant and you prefer to trigger via an external button, consider the DEZ-44-RS-A model which includes a separate start input
- Designed for industrial environments and compatible with power supplies, frequency inverters, and noise-sensitive equipment via galvanic isolation

Note: This model starts automatically when powered. If you need a functional device with start/stop/pause/reset, please check the DGZ advanced series section.
