5V Timer Switch Relay Module With Digital LED Display

The multifunctional relay control module is designed for people with different timing and control needs. It's perfect for many applications from hobby to industrial controls. This is a cycle delay timer module with an LED display. The module adopts MCU as the main chip, so it has high timer precision and reliable performance. Its working voltage is DC 5V and its working current is 50mA. You can use it to control the reciprocating stroke, or repetitive power on and off for equipment and products burn-in tests. Moreover, it can be widely used in timer operating equipment, repetitive testing circuit, and fish tank intermittent pumps. CityTech BD

1. Connection, wiring and more documentations

Operation Modes:

1. Upon signal is triggered(application of input voltage), the relay conducts OP time, then turn off. Operate within the OP period as follows. - 
2. Signal being re-triggered is ignored - 
3. Signal being re-triggered to reclock - 
4. Signal being re-triggered to reset, the relay contact disconnected, stop timing 
5. Feed trigger signal, the relay closed CL time, then conducts OP time. After timing, turn off the relay 
6. Feed trigger signal, the relay conducted OP time, the relay closed CL time, then repeat above actions, re-trigger signal within the timing cycle, the relay contact disconnected, stop timing. The circuit times(LOP) can be set. 
7. No need to trigger signal when power on, the relay conducts OP time, the relay closed CL time, then repeat above actions.The circuit times(LOP) can be set. 
8. The function of remaining signal: the timing will be reset upon signal is triggered, relay contacts stay connected. when no signal, turn off the relay after timing OP. During the period of timing, the timing will be reset upon signal is re-triggered. CityTech BD 

Timing Range:0.1 seconds (min.) ~ 999 minutes (max.) continuously adjustable

How to choose a timing range:

Upon setting the parameter value in the mode selection interface, select the timing range by short pressing the STOP button.

XXX. Decimal point at single digit, timing range = 1 second ~ 999 seconds.

XX.X Decimal point at tens digit. timing range = 0.1 second ~ 99.9 seconds

X.X.X. All the decimal points appear, timing range = 1 minute ~ 999 minutes.

For example, if you want to set the OP to 3.2 seconds, then move the decimal point to the tenth digit, the digital tube displays 03.2 CityTech BD 

Parameter explanation: OP = on time, CL = off time, LOP = cycle times (1 - 999 times, "---" stands for infinite cycles)

These parameters are independent each other, while they are shared by all operation modes.For example, when the OP(on-time) is set to 5 seconds in P1.1, the user wants P1.2 mode, then enter P1.2 to set the corresponding parameters, OP will also be 5 seconds.

In the main interface (digital tube displays 000), short press SET button, it will show OP (CL, LOP) and the corresponding time XXX

- If there is only OP (such as mode P1.1, P1.2, P1.3) time in the mode, then short press SET button will only display OP and the corresponding time.

- If there are OP, CL, LOP in the mode (such as mode P3.1, P3.2), short press SET button will display OP and corresponding time, CL and corresponding time, LOP and corresponding times.

After setting the operation mode, you can easily view and change the parameters by pressing the SET button in the main interface.

How to Set Parameters

1. First of all, determine the working mode of the relay. 
2. Upon the working mode of the relay, in the main interface (when the module is powered on, it will flash the current working mode - default P1.1 mode, and then enter the main interface) Long press the SET button for 2 seconds and release to enter the mode selection interface, select and set the mode (P1.1 ~ P-4) by short pressing the UP and DOWN buttons. 
3. Select a setting mode you want (Eg. P3.2), short press SET button to set the parameter. At that time, the parameter you set will flash (OP - ON time, CL - OFF time, LOP - cycle number). You could adjust the parameter by pressing UP and DOWN button. Long press (increase or reduce rapidly) and short press (increase or decrease by 1 unit) are supported. After setting the parameter, select the position of units point by short pressing “STOP” button to choose a timing range (corresponding time 0.1 seconds~999 minutes). Short press “SET” button to set the next parameter of current mode, the progress is as what have mentioned above. 
4. After selecting the mode’s parameter, long press the “SET” button for 2 seconds and release. The current setting mode will flash and return to the main interface, and the parameter setting is finished. It’s very simple! CityTech BD 

Relay Using Mode:

1. ON: Relay is allowed to conduct within OP time (on-time).
2. OFF: Relay is banned conducting and it is always at closing status. CityTech BD 

Short pressing “STOP” button in the main interface, you will realize the shift between “ON” and “OFF”. It will flash and return to the main interface. (This is acute stop function, one-button turn on and off the relay)

Sleep Mode:

1. C-P sleeping mode: When not using the relay for 5 minutes, the digital tube will turn off the display automatically, and the program will keep working.
2. O-d normal mode: Display of digital tube always on. Long press “STOP” button for 2 seconds and release to shift the status of C-P and O-d. It will flash and return to the main interface.
