Supports protocols such as Modbus and Profibus DP, and can be directly connected to old systems without major modifications. Plug it in and use it, debug quickly, maintain easily, upgrade mining equipment easily, save money and worry.
It must be! Specially designed for mine lifting, automatically suppressing cargo shaking. Real time speed adjustment during lifting, without shaking or shaking, to avoid damage to goods or injury to personnel, safe and efficient, and more reassuring for mining operations.
IP00 design but with dust and corrosion prevention treatment, 3M5 seismic standard can withstand mine vibrations. Equipped with a built-in C3 filter, it suppresses harmonic interference and is not afraid of heavy dust. The equipment runs stably, making it more reassuring for miners to use.
