Programmable Time Relay 220V | Digital Timer Module with Adjustable Timer and Interval

Programmable time relay with digital timer and dual LED display, ideal for automation and precise control of time intervals in 220V electrical applications.

Technical specifications:

Main features:

• Dual LED screen for setting two distinct time intervals: T1 and T2
• Wide timing adjustment range: seconds, minutes, or hours
• Flexible operating modes: delay, timing, loop (repetitive cycles)
• Stores set values even after power interruption

Common applications and usage examples:

• Pizza ovens: controlling baking cycle duration by switching power on and off at preset intervals.
• Pellet boilers: automating fan and burner cycles for efficient combustion control.
• Automatic lighting in greenhouses or aquariums: switching on and off at defined intervals for energy savings.
• Industrial automation: controlling equipment that requires intermittent operation, such as pumps, fans, or cooling systems.

Available operating modes:

• P1-0: after delay T1, the relay activates
• P1-1: after delay T1, the relay does not activate
• P1-2: after delay T1, the relay activates; after T2, it stops
• P1-3: after delay T1, the relay does not activate; after T2, it activates
• P1-4: repetitive ON/OFF cycles (ON after T1, OFF after T2, repeat)
• P1-5: repetitive OFF/ON cycles (OFF after T1, ON after T2, repeat)

Instructions for use:

1. Connect the module according to the wiring diagram in the pictures.
2. Power it with AC 220V. The display will show the default T1 time.
3. Briefly press the SET button to enter time setting mode. The digital tube will flash.
4. Using the + and – buttons, set the desired value for T1 (e.g.: ON duration).
5. Press SET to switch to T2 (e.g.: OFF duration) and set the desired value.
6. Press SET to save these settings or wait for automatic saving.
7. Press and hold the SET button to enter the parameter setting menu.
8. Set P0 for the time units:
• P0=0 – seconds
• P0=1 – minutes
• P0=2 – hours
9. Briefly press SET to switch to P1 and set the operating mode:
• P1=0 to P1=5 (according to the operating modes description above)
10. Briefly press SET to save and exit the settings menu.

Example of common setting (repetitive ON/OFF cycle):

If you want the relay to operate for 30 seconds and then stay off for 60 seconds, repeating this cycle, follow these steps:

1. Connect the module and power it according to the instructions.
2. Set T1 to 30 (seconds) – duration when the relay is active.
3. Set T2 to 60 (seconds) – duration when the relay is inactive.
4. Set P0 to 0 (time unit in seconds).
5. Set P1 to 4 (repetitive ON/OFF cycle mode).
6. Save the settings and let the module operate automatically in this cycle.
