The T3231 relay module is a programmable timer designed for industrial and electronic applications that require precise control of switching times. It can be programmed in multiple configurations, functioning as a timer, delay, cycle, or in manual mode. It features two displays that simultaneously show the two configurable times (T1 shown in red and T2 shown in blue), providing a clear view of the operating parameters.
Configuration is done using the dedicated UP, SET, DOWN, and RESTART buttons, which allow access to the menu and adjustment of values. Times can be set in seconds, minutes, or hours, within a range of 0 to 999, with an error margin of approximately 5%. An important advantage is that the program is retained in memory even if the power supply is interrupted.
The S1 and S0 pins act as an On/Off switch, which means the module has a passive output and must be connected in series with the load. In the off state, the output on S1 and S2 remains open, with no contact. The module also allows control via an external trigger (manual, with program P4=OFF), either by pressing the R button or by connecting an external switch on the PCB. Powered at 12VDC, the module features a 20A relay capable of switching loads up to 220VAC, 10A and a maximum power of 1500W (we recommend long-term use at half of the maximum specifications), making it suitable for a wide range of automation applications.
Warning: The module switches loads powered at 220VAC, a dangerous mains voltage. Connection and handling must be performed only with the power disconnected and by persons familiar with electrical safety rules. Contact with mains voltage can cause electric shock or death.

| Category | Function Code | Description |
|---|---|---|
| Time unit | P0-0 | Delay in seconds (0 – 999 seconds) |
| P0-1 | Delay in minutes (0 – 999 minutes) | |
| P0-2 | Delay in hours (0 – 999 hours) | |
| Operating mode | P1-0 | The relay activates after delay T1 |
| P1-1 | The relay deactivates after delay T1 | |
| P1-2 | The relay activates after T1, then deactivates after T2 (single sequence) | |
| P1-3 | The relay deactivates after T1, then activates after T2 (single sequence) | |
| P1-4 | The relay activates after T1, then deactivates after T2 (cyclic) | |
| P1-5 | The relay deactivates after T1, then activates after T2 (cyclic) | |
| Trigger mode | P4 = ON | Automatic mode (automatic trigger – default) |
| P4 = OFF | Manual mode (triggered by pressing the "R" button) |
Connection:

Use:
Program setting (P0, P1, P4):
Press and hold SET for about 3-5 seconds.
P0 or P1 appears on the red display.
Briefly press SET to switch between parameters (P0, P1, P4).
Use UP and DOWN to change the selected parameter value.
Wait about 6 seconds for saving.
Setting times T1 and T2:
Briefly press SET.
The red display (T1) flashes and you adjust it with UP or DOWN.
Press SET again.
The blue display (T2) flashes and you adjust it with UP or DOWN.
Press SET again or wait 6 seconds to save.
Manual start:
Enter settings according to the steps above.
Select parameter P4.
Set P4 = OFF.
The output will start only when you press the R (RESTART) button or an external button connected in parallel with it.
Quick configuration examples:
Relay starts after 10 seconds:
P0 = 0 (seconds)
P1 = 0
T1 = 10
Start for 5 seconds then stop:
P0 = 0
P1 = 2
T1 = 0
T2 = 5
Cycle 10 seconds ON / 20 seconds OFF:
P0 = 0
P1 = 4
T1 = 10
T2 = 20
