12V 24V DC Motor Controller Relay Board Forward Reverse Control Limit Start Stop Switch Pusher for Electric Curtain Automatic Door

12V 24V DC Motor Controller Relay Board Forward Reverse Control Limit Start Stop Switch Pusher for Electric Curtain

Key features

• Working mode 1: Self-locking mode, the signal only needs to be triggered once, and the module self-locking keeps running.
• Working mode 2: The automatic start version of mode 0 adds the power-on automatic start function on the basis of mode 0, that is, each time the module is powered on, it will automatically start forward rotation. This version is more suitable as a motion module between two points, and it will work automatically when the module is powered on.
• Working mode 3: Momentary mode. When there is a forward rotation signal, the motor rotates forward; when there is a reverse rotation signal, the motor reverses; when there is no forward rotation signal and no reverse rotation signal, the motor stops; when forward rotation, if there is a forward rotation limit, it will stop forward rotation; During rotation, if there is a reverse rotation limit signal, the reverse rotation will be stopped. Removing the two limit signals will not restore the rotation, and it is necessary to re-input the rotation signal to start the forward and reverse rotation.
• Working mode 4: The level-driven mode, similar in function to the H-bridge, operates according to the following logic: When there is a forward rotation signal and there is no signal at the forward limit, it will rotate forward; when there is a reverse signal and there is no signal at the reverse limit, it will reverse; this version is pure logic type, suitable for single-chip signal input. Pay attention to the forward rotation priority, that is, forward rotation is when both the forward and reverse input meet the conditions. Pay attention to the real-time nature of the level.
• Working mode 5: Start/Stop mode, the function is the same as mode 0, only the following function details are different: If the forward rotation has been started, input the forward rotation signal again, it will stop immediately; if the reverse rotation has been started, input the reverse rotation signal again, it will stop immediately. For example: there is a forward signal >>> forward rotation immediately; at this time, input the forward rotation signal >>> immediately stop forward rotation. Reverse the same.
• Working mode 6: The function is the same as mode 0, only the limit signal difference is as follows: The limit signal is only valid for the current time (the leading edge is valid). For example, after starting the forward rotation, it will stop when the forward limit signal is encountered. After the stop, although the forward limit signal is still input, the forward rotation can still be started by inputting the forward rotation signal at this time. When the unidirectional start and end points are on the same motion circle, this specification is usually used, for example, press once to make a circle, and press it again to make another circle.
