摘要： An intrinsically safe redundant regulator circuit includes a plurality of voltage limiting regulators between a regulated rail and a ground rail. Each of the plurality of voltage limiting regulators includes: (i) a shunt regulator component configured to clamp a voltage across the regulated rail and the ground rail to a safety clamp voltage value; and (ii) one or more components, where a property of each of the one or more components is selected to configure the safety clamp voltage value.

摘要： A diagnostic device is physically coupled to a control device in a process control system, and includes an accelerometer that determines when a motion or vibration of the control device is greater than a predetermined threshold. When this condition is detected, one or more other components of the diagnostic device (e.g., processor, communication module, etc.) are activated, and a distress signal is transmitted from the diagnostic device using the activated components. Consequently, the duty cycles of components of the diagnostic device are decreased and optimized, leading to significant power savings. Indeed, in some embodiments, energy harvesting may be sufficient to power the diagnostic device. Further, in some embodiments, the diagnostic device may not require a component processor.

摘要： Techniques for diagnosing failures in a digital solenoid I/P converter are provided herein. A controller of the I/P converter may apply a fixed voltage to an I/P coil of the I/P converter, causing an armature to move from an off-position to an on-position in a properly-functioning I/P converter. The controller may receive an indication of whether a digital logic line trip has occurred, indicating that a current for the I/P coil has reached a desired maximum current level. The controller may remove the fixed voltage applied to the I/P coil when the maximum current level is reached or when a threshold period of time has elapsed from the application of the fixed voltage to the I/P coil. The controller may diagnose, based on whether the digital logic line trip occurred prior to removing the fixed voltage, a failure in the I/P converter.

摘要： An apparatus includes a housing, a touch sensor, a display, and a control module. The housing has a body defining a volume to accommodate a process control device and is adapted to withstand a threshold internal pressure greater than an external pressure. The housing further has a transparent portion having first and second surfaces. The touch sensor is disposed adjacent to the second surface of the transparent portion and senses an input received within a minimum distance from the first surface of the transparent portion. The display is disposed adjacent to the touch sensor and displays at least one adjustable variable corresponding to the process control device.

The controller may compare the amount of time elapsed from the application of the fixed voltage to an expected amount of elapsed time from the application of the fixed voltage to the I/P coil after which a digital logic line trip will occur for a properly functioning I/P coil and diagnose, based on the comparison, a failure in the I/P converter.
