Eight-Channel Variable Frequency Weight Acquisition Feedback Display Wireless Remote Controller For Cranes
Description:The entire set includes 1 transmitter+1 receiver+1 analog input collector, with a built-in receiver and an external extended suction cup antenna.
Once the weight exceeds the set upper limit value, it can only descend and cannot ascend. At this time, the remote control has a self program judgment internally and automatically determines the action control logic of only descending but not ascending.
Product model DHQ-6FD12KMR (ACDC12-24V/open space of 100 meters/1 generator, 1 receiver, 1 acquisition/16 switching values+1 emergency stop/bidirectional feedback analog input weight/limit weight only decreasing logic judgment), other voltages such as AC220V or AC380V are adapted through external transformer voltage conversion
If the receiver directly outputs RS485, it is directly connected to the overload limiter with RS485 interface, and there is no need to lay out the collector separately. Other voltages such as AC220V or AC380V are adapted through external transformers.
Product highlight: Good anti-interference performance, with unique identification codes between each remote control transmitter and receiver, reaching hundreds of millions of sets, never repeating, and strictly avoiding mutual interference and potential interference. And the remote control has up to 50-256 frequency points, and each set in the same environment can be configured with separate frequency points. Even if the frequency points overlap, given the uniqueness of the ID identification code, there will be no impact on each other, ensuring safety and reliability.
Usage: crane, overhead crane, crane, electric hoist, gantry crane, cantilever crane, portal crane, port crane, wharf crane, ship crane, bridge erecting machine, beam lifter, etc. within the 4-point switching value, as well as elevators, hoists, lifting platforms, winch, motors, plate shears.
