Abstract: An industrial communication module includes a controller and a common interface coupled to the controller. The common interface is configured to couple to a plurality of different types of sensor modules. The industrial communication module includes protocol/output circuitry coupled to the controller and configured to provide an output to a remote device. A sensor module includes a controller and a common interface coupled to the controller. The common interface is configured to couple to a plurality of different types of industrial communication modules. The sensor module includes measurement processing circuitry coupled to the controller and configured to measure an analog electrical characteristic of a sensor and provide a digital indication of the measured analog electrical characteristic to the controller.

Abstract: A compressor system operable to shutdown in response to a shutdown signal. The compressor system includes a compression device operable between a first speed and a second speed to produce a flow of compressed fluid at a pressure. A blowdown valve is movable between a closed position and an open position in which at least a portion of the flow of compressed fluid passes through the blowdown valve to reduce the pressure of the flow of compressed fluid. A sensor is positioned to measure the pressure and a controller is operable to move the blowdown valve to the open position and set the speed of the compression device to a low set point speed in response to the shutdown signal.
