The MineWATCH PC21 Environmental Monitoring solution can be either a simple system or as complex as required to make sure the environment is safe. Each PC21-1 module has 14 analogue/digital inputs and 6 output relays, the use of there and the control function it is designed to meet the end user requirements. Simple systems which require additional monitoring can be easily expanded by adding extra PC21-1 modules on Canbus (up to a distance of 500m) or on canbridge (up to a distance of 5000m).
Different types of Gas Sensors can be connected to the system either:-
The use of modbus connected sensors is increasing, especially in Russia. The benefits from modbus sensors are:
All the data that is collected by the PC21 system is passed automatically via SAP modem or Fibre Optic Ethernet transmission to the surface control room and using the MineSCADA computer control system the data is displayed on the operators computer screen. All the data is saved on the dual servers and available on every MineSCADA computer that is connected on the network.
