KT670-F Broadcast Substation

The KT670-F intrinsically safe broadcast substation for mines is intrinsically safe, which is small-sized, lightweight and easy to install and maintain. Due to the built-in optoelectronic module, the substation can be networked through optical cables. The substation also integrates the broadcast and IP phone, which is used as a broadcast substation in an emergency and IP phone under normal circumstances. The external dial pad of the substation can be used for communication with the dispatching center and other broadcast substations.
