1. What is the PO version? PO is a self-locking mode. When the external forward switch (K1) is pressed, the motor will immediately rotate forward. Once activated, the motor continues running forward even after the switch is released, and it will only stop upon receiving a reverse rotation signal (K2) or a forward rotation stop signal (SW1). 2. What are the signal requirements? Can a sensor be connected? The signal input is active low and compatible with a three-wire NPN-NO type sensor. K1, K2, SW1, and SW2 follow this specification. 3. What is the limit signal? 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 if the signal is removed. The forward rotation must be reactivated to resume operation. 4. What are the input and output voltages? The TKS-M8 input voltage range is 4V–40V. For reliable operation, use within 6V–36V. The output motor voltage matches the input voltage. Working voltage: Wide voltage DC 4V–40V Module power consumption: 0.6W (without load motor), 0.1W static Signal input: Active low level, connected to the negative side of the optocoupler. A voltage below 2V is considered an active signal Response speed: 20ms for K1 and K2, 50ms for SW1 and SW2 Output current: 20A Action life: 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 Size: 83x46x20mm Package Contents: 1 x PO Forward/Reverse Controller Only the above content is included; other items are not included Note: Lighting and display differences may cause slight color variations between the image and the actual item.
