DC 6V 12V 24V Motor Forward Reverse Controller 20A High Current Limit Relay Driver Board

DC Motor Forward and Reverse Regulator with Limit Relay Driver This DC motor control board provides reliable forward and reverse regulation for 6V, 12V and 24V systems, with a 20A high current capacity. Designed for lifting and positioning applications, it combines a limit relay driver with straightforward push-button control, making it a practical choice for a range of motor control tasks. Signal and Connection Requirements The control board accepts an active low signal and is compatible with three-wire NPN-NO type sensors. The K1, K2, SW1 and SW2 terminals all follow this same specification, so you can connect your existing sensor setup without additional conversion hardware. Limit Signal Operation The limit signal, also referred to as a stop signal, is trigger type and level activated. When a short limit signal occurs during forward rotation, the motor stops immediately and remains stopped even after the limit signal is removed. To resume forward movement, you must restart the forward rotation signal, giving you positive control over the stopping position. Self-Locking PO Mode The PO version operates in self-locking mode. When the external forward switch K1 is pressed, the motor begins rotating forward and continues to do so even after the switch is released. The motor only stops when it receives the reverse turn signal K2 or the forward turn stop signal SW1, allowing hands-free operation once movement has been initiated.
