MineWATCH PC21-2T Transmission Module

The PC 21-2T module is equipped with an intrinsically safe barrier and telemetry modem to provide a long range telemetry link to a SCADA system to provide remote control and monitoring facilities. The telemetry link is designed to use 4 core twisted pair telephone cable and is capable of operating over distances of up to 10km. Up to fifteen PC 21-2T modules can be connected to a single telemetry ring or spur.

The MineWATCH PC 21-2T module also has a cluster CAN bus data link enabling it to be connected to a cluster of up seven other modules, typically a PC 21-2D display module and a number of PC 21-1 control modules.

In common with other MineWATCH PC 21 modules, the PC 21-2T module is powered from a 12 volt dc 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.
