1When the external forward rotation switch (K1) is pressed, the motor will immediately rotate forward. At this time, the instant switch will be released and the motor will continue to rotate forward. It will not stop until the reverse rotation signal (K2) or the forward rotation stop signal (SW1) is encountered. 2Copper wiring terminal, strong overcurrent ability and low heat. 3The inputs are all optocoupler coupling, which is resistant to transient interference. 44V~40V input, DC voltage regulation, low power consumption, stable operation. 520A relay, strong load capacity.
