12 24V DC Motor Reverse Forward Switch Overcurrent Protection 8A Wireless Remote Control Forward Reverse Switch Relay
Product Description
Power supply: optional DC12V/24V Input signal: forward, reverse, positive limit, negative limit [High level DC4-26V (PNP sensor or contact switch)] Motor action: forward, reverse, cycle forward and reverse Protect: 1. Motor stalled and over-current stop 0-8A can be manually set (2S after over-current does not trigger to prevent module burnout) 2. Limit control (the direction will not be triggered after the limit) Function: 1. Jog forward or reverse rotation (200mS delay for forward and reverse switching) 2. Self-locking forward or reverse rotation (200mS delay for forward and reverse switching) 3. Power cycle forward and reverse (forward and reverse switching has a 200mS delay)
1. Function setting:
[1] The module is powered on. [2] Long press the setting button for 1 second to enter the mode. The setting mode indicator flashes on, (the number of flashes corresponds to the number of modes), short press the setting button to switch modes. (There are three modes, mode 1 to mode 3 cyclically switch). [3] Press the setting button again for 1 second to enter the current setting, the current indicator flashes on, (the number of flashes corresponds to the current gear), short press the setting button to switch the protection current (the protection current is divided into 6 levels on average, 1 level is the smallest, and 6 levels The maximum protection current of the module is 8A, and the 1st to 6th gears can be switched cyclically). Program-controlled locked-rotor current 1-8A can be set accurately and stably. [4] Finally, press and hold the setting key for 1 second to save the setting, and the module will start to work, and the module will be used directly without losing the parameters when it is powered off.
Application scenario
Wireless remote control settings Mode setting and learning: 1) Short press LK once, the LED flashes once, release the button 1 second after the LED is always on, set the working mode to 4-way output jog mode, and enter the learning mode, press any button on the remote control within 5 seconds to complete the learning. After the learning is successful, the LED will be off. If the remote control button is not pressed within 5 seconds, the LED will also be off and the learning mode will be exited. 2) Short press LK twice, LED flashes twice, other information is the same as 1) 3) Short press LK 3 times, LED flashes 3 times, other information is the same as 1) 4) Short press LK 4 times, LED flashes 4 times, other information is the same as 1) 5) Short press LK 5 times, LED flashes 5 times, other information is the same as 1) 6) Short press LK 6 times, LED flashes 6 times, other information is the same as 1) 7) Short press LK 7 times, LED flashes 7 times, other information is the same as 1) 8) Short press LK 8 times, the LED flashes 8 times, after releasing the button, the LED goes out to clear all saved states (code pairing) and the working mode is restored to the 4-way jog mode at the factory. 9) The factory default of the module is 4-way jog mode.
Applications
1. Car glass lift (the signal can no longer trigger the forward rotation after the forward rotation limit is triggered; the signal can trigger the forward rotation again after the motor overcurrent stops) Use single-pole double-throw jog switch, connect the two output signals of the switch to the forward and reverse trigger ports respectively, set the over-current gear to the motor locked-rotor current, the forward signal is triggered, the glass runs up, and the glass rises to the position When the motor is blocked, the controller controls the motor to stop. 2. Automatically open the glass sliding door (After the forward rotation limit is triggered, the signal can no longer trigger the forward rotation) The human body infrared detection module drives a single-pole double-throw relay module. The common point of the relay module is connected to the high level, the normally open and normally closed are respectively connected to the forward and reverse signal ports, and the limit switch is connected to the limit signal port. The human body infrared detection module detects that someone is approaching, and the output high level triggers the relay module to pull in, the normally open point and the common point are connected, and the output high level is triggered. The module forward rotation signal port is triggered, the motor rotates forward, and the limit switch reaches the limit point. Triggered and the motor stops. When the person leaves, the human body infrared detection module outputs a low level, the relay is disconnected and the normally closed port outputs a high level, the module is triggered to reverse the port, the motor reverses, and the limit switch is triggered when the limit point is reached, the motor stops, and the door closes. 3. The realization process of the logistics locker/automatic gate lifter/home automatic cabinet/automatic mixer is similar to the above case process. (Automatic control, overcurrent protection)

Remark
|
|||
|
Model 1
|
Jog, forward, or reverse
|
When there is a forward signal, the motor rotates forward; when there is a reverse signal, the motor reverses; when there is no forward signal, the motor stops when there is no reverse signal.
|
After reaching the forward limit, it can’t rotate forward again, and after reaching the reverse limit, it can’t reverse again. The limit signal has priority. When rotating, it will stop immediately when it encounters the limit signal.
|
|||
|
Model 2
|
Self-locking, forward or reverse
|
The signal only needs to be triggered once, and the module self-locking runs all the time. When a reverse signal is encountered during forward rotation, it will reverse immediately.
|
After reaching the forward limit, it can’t rotate forward again. After reaching the reverse limit, it can’t rotate again. The limit signal has priority. When rotating, it will stop immediately when it encounters the limit signal.

|
Model 3
|
Energize, cycle, twist
|
The power-on module will automatically trigger a forward rotation, (in this mode, the limit switch is used to trigger the motor to
automatically rotate forward and reverse). The motor runs to the forward limit switch; the limit switch triggers the reverse signal, the motor reverses, and the motor runs to forward Rotation limit switch; limit switch triggers a forward rotation signal, and the motor rotates forward. Keep looping. |
To realize the mode 3 function, it is necessary to connect the output signal of the limit switch to the motor forward and reverse trigger port.

Installation Instructions
Wireless remote control port introduction
GND: negative pole of power supply VCC: Positive power supply (typical +3. 3V) DO: The first switch output, usually low level, high level when controlled D1: The second switch output, usually low level, high level when controlled D2: The third switch output, usually low level, high level when controlled D3: The fourth switch output, usually low level, high level when controlled LK: External LED and button multiplexing pin, can be left floating if not connected PD: Sleep pin (connected to VCC to sleep, and cannot receive signals after sleep: grounding work) GND: negative pole of power supply GND: antenna ground ANT: Antenna The receiving board sleeps by default, you need to short the PD port and GND
Wiring steps:
1. Short-circuit the PD port and the GND next to it 2. Solder VCC and GND to the two ends of the C2 capacitor on the main board. Pay attention to the positive and negative poles. The positive pole is close to the blue relay. 3. Connect D3~D0 to forward rotation, reverse rotation, positive limit and negative limit 4. Power on the forward and reverse controller, short press the button on the wireless receiving board once, wait for the wireless receiving board. The light on the wireless receiving board is always on, long press any button on the remote control until the wireless receiving board light goes out, and the wireless setting is successful.
Note
The above wiring diagram is based on the limit switch control method. It can also be controlled by the locked-rotor current. At this time, the limit switch can be connected or not connected.
