1. PO version refers to the self-locking mode. When the external forward switch (K1) is pressed, the motor will immediately rotate forward. Once activated, the motor continues to run forward even after the switch is released. The motor will only stop upon receiving a reverse rotation signal (K2) or a forward rotation stop signal (SW1). 2. The control signal is active low. A three-wire NPN-NO type sensor can be used. K1, K2, SW1, and SW2 follow this specification. 3. The limit signal acts as a stop signal. It is trigger-type and level-enabled. If a short limit signal is encountered during forward rotation, the motor will stop and remain stopped even after the signal is removed. The forward rotation must be reinitiated to resume operation. 4. Input voltage range for TKS-M8 is 4V–40V. For reliable operation, use within 6V–36V. Output voltage to the motor matches the input voltage. Working voltage: Wide voltage DC 4V–40V Module power consumption: 0.6W (no load motor), 0.1W in standby Signal input: Active low level, connected to the negative side of the optocoupler. A voltage below 2V is recognized as a valid signal Response speed: 20ms for K1 and K2, 50ms for SW1 and SW2 Output current: 20A Operating life: Greater than 150,000 cycles PO/Standard version: After a short trigger, the motor remains running until a limit or commutation signal is received Color: Green Material: PCB Dimensions: 83 x 46 x 20mm Package Contents: 1 x PO Forward/Reverse Controller Note: The package includes only the items listed above. Other products are not included. Note: Lighting and display differences may cause slight color variations between the image and the actual item. Measurement may vary by ±1–3cm.
