MineWATCH PC21-1 Control Module

The PC 21-1 Control module is used to interface with mine plant.  In common with all the MineWATCH PC 21 modules it is intrinsically safe and is powered from a 12 volt intrinsically safe power supply.  This can be a separate power supply, or from a common power supply feeding several modules via the cluster CAN bus.

The MineWATCH PC 21-1 module is housed in a suitable enclosure and equipped with the necessary terminals for connecting the incoming and outgoing cables.  It has up to 14 digital or analogue inputs, up to six voltage free changeover relay contact outputs and up to two optional voltage or current analogue outputs.

The module can be fitted with an optional 2 line 16 character LCD local display assembly which also has four buttons to navigate the various display screens.

There are two CAN bus data link outputs, one is a high speed 125kbs cluster data link to enable up to seven other modules to be connected, with up to 500 metres of cable linking the modules. This cluster data link can be used to connect to a PC 21-2D display module, a PC 21-2T data transmission module and a number of additional PC 21-1 control modules to form a cluster of up to eight modules in total.

The second data link is a low speed 10 kbs CAN bridge link enabling up to eight clusters to be interconnected with up to 5km of cable.
