Timer relay module (FRM02), 12V version (power supply for the module)
Switching voltage up to 220V AC.
Operating instructions
The multifunctional relay control module (FRM02), uses an internal microcontroller as the main control unit and includes 18 preset types of functions.
These modes can be customized based on user requirements. The two relays can be programmed separately and independently.
I. Module function
The user can select one of the following 18 types of functions using the buttons on the circuit board
Functions 1-8 start automatically after the module is switched on.
Functions 9-18 start after a signal input (high-level pulse signal trigger) with a high-level duration of ≥ 20 ms.
Mode1
Timing pull-in:

T1 can be set between 0.1 seconds and 270 hours.
If a high-level signal is applied to contact CH1, the relay is deactivated and timer T1 starts again.

II Setting the operating modes
The user can set the operating mode using the buttons and the display. All parameters are saved automatically after setting.
Buttons: There are 4 buttons, namely: [SET] [SM1], [NUM +] and [NUM-],
The buttons recognize short and long presses.
Short press means that you press the button for less than 1 second.
Long press means that you press the button for more than 1 second.
Operating mode: There are 3 types, namely: [Operating mode], [Parameter view
Mode] and [Parameterization mode].
[Digital displays]: There are 4 digital displays used to set or display user timing
[LED]: 4 blue parameter indicators, 1 red operation indicator on the power connector.
[User parameters]:
4 types of parameters can be set (4 blue LED lights).
[MD]: MD, display shows the current program mode. A total of 18 modes are available for selection (01-18).
[T1]: T1 LED, display shows the time T1, can be 0-9999 seconds.
[T2]: T2 LED, display shows time T2, can be 0-9999 seconds.
[NX]: NX LED, display shows the different meanings depending on the function.
1. NX meaning
In functions 1-6 and 11-16, the NX LED in the display shows the time base.
Time base means that the numerical values entered in T1 and T2 are multiplied by the values in the NX specification.
For example: NX displays "01 01".
This means that the timing time unit is 1 second.
For example: NX displays "10 02".
This means that the timing time unit of T1 is 10 seconds, T2 is 2 seconds.
The value 10 is then multiplied by the value of T1 to calculate the timer T1.
The value 2 is then multiplied by the value of T2 to calculate the timer T2.
The maximum time can be set by this multiplication with 9999 (T1) x 99 (NX) seconds, which corresponds to approximately 270 hours.
2. NX meaning
In functions 7, 8, 17 and 18, the NX value on the display indicates how many cycles are to be carried out in the respective mode.
In these modes, the times for T1 and T2 cannot be multiplied by the "NX" value.
Operating mode
1. When the module is switched on, a short countdown starts. The current function number is then displayed.
Example: (1 - 0 1 ) means "Relay no.1 with function01.
Example: (2 - 0 1 ) means "Relay no. 2 with function01.
2. Press [SET] briefly to enter energy saving mode, the display goes out but the program continues to operate normally. Press [SET] again to restore the display.
3. Press and hold [SET] to enter parameter setting mode.
4. Long press [SWI] to enter the parameter view mode.
5. Long press [NUM+] to enter automatic power saving mode for 10 seconds.
The display flashes twice, indicating that the setting was successful. After activating the energy saving mode, if no button is pressed within 10 seconds, the display is switched off but the program continues to run.
You can also long press [NUM+] again to exit automatic mode.
6. Long press [NUM-] to reset and stop the timing. Briefly press [NUM-] again to restore the timing. After resetting, the LED lights no longer flash.
Parameter view mode
Press and hold [SWI] to enter parameter view mode. This mode can display the parameters of the current function
Briefly press the [SET] button to change the parameters.
Long press the [SM1] button to enter [Operating mode];
Parameter setting mode
Press and hold [SET] to enter parameter setting mode. Various parameters can be set in this mode, for example you can set the mode 1 to 18 and the times T1 and T2 as well as NX.
1. Briefly press the [SET] button to change the parameters, you can select one from [MD] (mode 1-18). [T1], [T2] or [NX], the LED indicator of the selected parameter shows the set parameters on the display.
2. Briefly press the [SWI] button to access the setting for time T1; the blue LED labeled T1 lights up as a check.
Use the SM1, NUM+ and NUM- buttons to set the desired time.
3. Briefly press the [SWI] button to access the setting for time T2; the blue LED labeled T2 lights up to indicate this.
Use the SM1, NUM+ and NUM- buttons to set the desired time.
4. Briefly press the [SWI] button to access the NX time setting; the blue LED labeled NX lights up to indicate this.
Use the SM1, NUM+ and NUM- buttons to set the desired numbers.
5. Press and hold the [SET] button, save the parameters and call up the operating mode.
Example 1
Control a lamp that is to be on automatically for one hour via relay no. 1 and then switch it off.
This application can use Mode2 or Mode12:
MOD="1 - 12"
T1=3600
T1="xxxx" (not required)
NX="0 1 x x "(x can be any value, not required)
Run:
1. Long press [SET] to enter the parameter setting mode;
2. The MOD LED lights up, press [NUM+] or [NUM-] and set the following on the display "1 - 12". (This corresponds to mode 12)
3. Briefly press "SET", T1 LED lights up. Now set via the display = "3 6 0 0". T2 is not required.
4. Briefly press "SET" and set at NX="0 1 0 1"
5. Press and hold [SET], save the settings and exit parameter setting mode. The function starts immediately.
Example2
When switched on, the machine runs via relay2 for one hour, then stops for 10 minutes and repeats this for 5 cycles. The machine then switches itself off.
This application can be realized with Mode8.
Parameter:
MOD="2 - 0 8"
T1="3 6 0 0"
T2="0 6 0 0"
NX="0 0 0 5"
