The ZH2051 speed impact sub monitoring device prolongs the service life of the equipment. The bus recognizer is the core conversion unit of the intelligent centralized lubrication system. As a bridge between the main control cabinet and the on-site oil feeder, it can accurately decode the matrix control code signals sent by the PLC and automatically recognize instructions to control the corresponding electromagnetic oil feeder. This device supports flexible expansion of lubrication points, especially suitable for large equipment with dense lubrication points that require centralized control, significantly improving system management efficiency and reliability.
