MineWATCH PC21 General Purpose Control Unit

The MineWATCH General Purpose Control unit is intended for various applications, including pump control, fan control, auto-loop control, hydraulic coupling control or compressor control.

The basic unit contains a PC 21-1 control module and a PC 21-2D display module, although other combinations of module are possible. T

The unit is powered from a separate 12 volt intrinsically safe power supply, a power supply unit with interposing relays can be bolted directly to the General Purpose unit as in the case of the conveyor control unit as previously described if required. This power supply can be used to power several PC 21 modules via the cluster CAN bus.

The Cluster CAN bus can be connected to other modules and units as required provided the maximum number of modules is limited to 8 in a single cluster.
