DC 6V 12V 24V Motor Forward Reverse Controller 20A Heavy Duty with Limit Switch for Lift Applications 1. What is the PO versions? PO is self-locking mode. For example, when the external forward switch (K1) is pressed, the motor will immediately rotate forward. At this time, the switch will be released immediately, and the motor will still keep rotating forward. It will not stop until it encounters the reverse rotation signal (K2) or the forward rotation stop signal (SW1).<br> 2. What are the requirements for the signal, can the sensor be connected? The signal is active low, it can be a three-wire sensor (NPN-NO type), K1 K2 Sw1 SW2 is still this specification.<br> 3. What is the limit signal? The limit signal can also be called a stop signal. The limit signal is trigger type and level-enabled. For example, if a short limit signal is encountered during forward rotation, it will stop, even if the limit signal disappears, it will still stop. The forward rotation signal must be restarted to run forward again.<br> 4. What is the input and output voltage? The input voltage range of TKS-M8 is 4v-40v, but to reliable operation, it is recommended to use it in the range of 6V-36V. The output motor is the same as the input voltage.<br> Working voltage:wide voltage DC4V-40V<br> Module power consumption:0.6W (without load motor), static 0.1W<br> Signal input:active low level, the input is the negative pole of the optocoupler. When the voltage is lower than 2V, it is considered that there is a signal<br> Response speed:K1 K2 is 20mS, SW1 SW2 is 50mS<br> Output current:20A<br> Action life: 150,000 times<br> PO/Standard version:After a short trigger, the motor will keep running until it encounters a limit or commutation signal<br> Colour:Green<br> Material:PCB<br> Size:83x46x20mm<br> Package Contents:<br> 1 * P0 Forward/reverse controller<br> Only the above package content, other products are not included.<br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
