ABSTRACT:
A coating material dispensing system comprises a hazardous area and a non-hazardous area. Multiple coating material type controls have coating material input ports, coating material output ports, and control ports for controlling the passage of a type of coating material controlled by each respective coating material type control from its input port to its output port. A controller generates control signals for controlling the multiple coating material type controls. The control signals are multiplexed in the non-hazardous area, and transmitted into the hazardous area where they are demultiplexed and provided to the coating material type controls. The demultiplexer and coating material type controls are intrinsically safe.
