DC Motor Forward Reverse Controller, 20A High Current, 4V-40V Wide Voltage, PO Self-Locking Mode, for Automation DIY Projects (2 Pack)

Features:1. PO Self-Locking Mode: When the forward switch (K1) is pressed, the motor starts and continues running forward even after releasing the switch. It only stops when a reverse signal (K2) or stop signal (SW1) is received.2. Signal Compatibility: All inputs (K1, K2, SW1, SW2) use active-low logic, compatible with three-wire NPN-NO sensors and standard switches.3. Limit Signal Function: The stop signal works in trigger or level-enabled mode. For example, a brief limit signal during forward rotation stops the motor and holds it stopped until the forward signal is reactivated.4. Wide Voltage Range: Compatible with input voltages from 4V to 40V (recommended 6V–36V). The motor output voltage matches the input, ensuring stable operation across different power sources.5. Durable & Efficient Design: Built with a green PCB, consumes only 0.6W under no load (0.1W static). Fast response (20ms for K1/K2, 50ms for SW1/SW2), handles up to 20A output, and rated for 150,000 operation cycles.Product Details:This forward/reverse motor controller provides stable, high-current control for DC motors. It supports wide voltage operation (4V–40V) and low-level signal inputs, making it compatible with sensors and switches. The PO self-locking mode keeps the motor running until a stop or reverse command is given. Compact size (83×46×20mm) makes it ideal for automation, DIY projects, and industrial applications requiring reliable direction control.Specifications:- Working Voltage: DC
