Feature Highlights: 1. PO Version Explained: The PO version features a self-locking mode. For example, when the external forward switch (K1) is pressed, the motor starts rotating forward immediately. Even after releasing the switch, the motor continues to run forward. It only stops when it receives a reverse signal (K2) or a forward stop signal (SW1). 2. Signal Compatibility: The signal operates on active-low logic and is compatible with three-wire sensors (NPN-NO type). All inputs—K1, K2, SW1, and SW2—follow the same specification. 3. Limit Signal Function: The limit signal (also called a stop signal) works in trigger or level-enabled mode. For instance, if a brief limit signal is detected during forward rotation, the motor stops and remains stopped even after the signal disappears. To resume forward motion, the forward signal must be reactivated. 4. Wide Voltage Range: The TKS-M8 supports an input voltage of 4V–40V, with a recommended operating range of 6V–36V for reliable performance. The motor output voltage matches the input voltage. 5. Durable & Efficient Design: Built with a green PCB, the module consumes only 0.6W under no load (0.1W static). It responds quickly (20ms for K1/K2, 50ms for SW1/SW2), handles up to 20A output, and is rated for 150,000 operation cycles. Product Details: This forward/reverse motor controller offers stable, high-current control for DC motors. It supports wide-voltage operation (DC 4V–40V) and features low-level signal inputs compatible with sensors and switches. With self-locking logic in PO mode, the motor continues running until a stop or reverse command is received. Compact in size (83×46×20mm), it is ideal for automation, DIY projects, and industrial applications requiring reliable motor direction control.
