Application of DM-900 in the Coal Mining Industry

The DM900 is applied in explosion-proof high and low voltage switchgear products used in the underground mines of a large state-owned coal mining group. By installing one DM900 device at each end of both the explosion-proof high-voltage switchgear and low-voltage switchgear, the RS485 monitoring parameters from the explosion-proof low-voltage switchgear can be transmitted to the high-voltage switchgear end. These parameters are then collectively reported to the above-ground monitoring room through the interface at the high-voltage end.
