Abstract

See full text

A wireless sensor network gateway includes safe side circuitry, hazardous side circuitry and isolation circuitry, which are supported by a housing. The safe side circuitry includes a safe side power circuit, and a safe side data input/output (I/O) circuit. The hazardous side circuitry includes a hazardous side power circuit, and a hazardous side data I/O circuit. The isolation circuitry divides the safe side circuitry from the hazardous side circuitry. The isolation circuitry includes a power isolation circuit that couples the safe side power circuit to the hazardous side power circuit and forms an intrinsic safety barrier between the safe side power circuit and the hazardous side power circuit, and a data isolation circuit that couples the safe side data I/O circuit to the hazardous side data I/O circuit and forms an intrinsic safety barrier between the safe side data I/O circuit and the hazardous side data I/O circuit.
