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. Even if the switch is released, the motor will continue rotating forward until it receives 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 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 after the signal is removed. The forward rotation signal must be reactivated for the motor to run forward again. 4. What are the input and output voltages? The input voltage range for the TKS-M8 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 (no load motor), 0.1W static Signal input: Active low level, connected to the negative side of the optocoupler. A voltage below 2V is considered a valid signal Response speed: 20ms for K1 and K2, 50ms for SW1 and SW2 Output current: 20A Operational life: 150,000 cycles PO/Standard version: After a short trigger, the motor continues 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 items are included; other products are not included.
