- Optocoupler isolated inputs provide resistance to transient interference, ensuring reliable control from low-voltage controllers or PLCs. - CW and CCW motor direction control with a simple forward switch: pressing the external forward switch (K1) makes the motor rotate forward; releasing K1 stops the motor immediately. - High load capability thanks to a 20A DC relay, suitable for motors and actuators with higher current requirements. - Wide DC input range from 4V to 40V, with DC voltage control and low power consumption for stable operation. - 24 V motor copper cable connections deliver reliable wiring, strong overcurrent capability, and low resistance for efficient performance. - Robust and compact design intended for easy integration with existing motor systems and control circuits. - Compatibility: suitable for microcontroller or PLC-based control through optocoupler inputs, enabling safe interfacing with various systems. Applications and scenarios - Robotics projects requiring simple forward/reverse control and immediate stop for precise maneuvering. - Small automation setups such as conveyor segments, linear actuators, or door actuators that run on 4–40 V DC supplies. - Hobby projects or educational kits where isolated control signals and reliable high-current switching are important.
