    Abstract: A system includes a module having at least one input/output (I/O) channel. The system also includes a terminal block having terminals configured to provide electrical connections for the at least one I/O channel. The system further includes a barrier assembly having one or more intrinsic safety (IS) barriers. Each IS barrier is configured to receive at least one data or power signal, limit an amount of energy in the at least one data or power signal, and output the at least one energy-limited data or power signal. Each IS barrier includes at least one limiter circuit configured to limit the amount of energy in the at least one data or power signal. Each IS barrier is configured to be mounted on the terminal block. Each IS barrier could be configured to provide galvanic isolation between multiple devices or systems coupled to the IS barrier. Each limiter circuit could include a current limiter.

    Abstract: An apparatus includes at least one processor configured to obtain inline measurements of one or more properties of crude oil, translate the measurements into a set of process and control parameters, and apply the process and control parameters to process equipment. The process and control parameters configure the process equipment to process the crude oil having the one or more properties. The one or more properties of the crude oil may include at least one of: density, specific gravity, viscosity, carbon residue, and sulfur content of the crude oil. The process and control parameters could be applied to one or more controllers associated with a blending unit in a refinery or to one or more controllers associated with a crude oil distillation column in the refinery.

    Abstract: An apparatus includes first and second hardware components. The first component includes at least one first input configured to receive at least one first data or power signal, at least one voltage clamping circuit configured to limit a voltage of the at least one first data or power signal, and at least one first output configured to provide the at least one voltage-limited first data or power signal. The second component includes at least one second input configured to receive at least one second data or power signal, at least one limiter circuit configured to limit an amount of energy in the at least one second data or power signal, and at least one second output configured to provide the at least one energy-limited second data or power signal. The at least one second data or power signal comprises or is based on the at least one voltage-limited first data or power signal.
