摘要： An intrinsically safe microprocessor controlled pressure regulator for operation in a hazardous environment. The intrinsically safe microprocessor controlled pressure regulator receives control commands that are input to a microprocessor in the hazardous environment. The microprocessor generates control commands to control operation of an intrinsically safe solenoid valve and an intrinsically safe piezo electric valve. The piezo electric valve generates an output signal for controlling operating parameters of the paint gun. One or a plurality of microprocessors may operate within a hazardous environment in order to control one or a plurality of intrinsically safe valves in the hazardous environment.

摘要： To detect a power supply failure on an intrinsically safe field bus of a manufacturing process control system in an efficient manner there is provided a field device with a discharge protection unit which is connected to a control bus (10) for supply of an operating current from the control bus (10) to the field device (20, 22). The discharge protection unit (32) inhibits a discharge of energy stored in the field device (20, 22) to the control bus (10). The field device also comprises a controller unit (38) adapted to control the operation of the field device (20, 22) and being powered with the operating current from the control bus (10). According to the present invention the discharge protection unit (32) comprises at least two rectifying elements inserted into the current path of the operating current with identical conducting directions and an input signal or an output signal of a selected rectifying element is supplied as interrupt signal to the controller unit (38) for power supply failure detection.

摘要： Disclosed is a circuit arrangement (105) for a field device (101). Said circuit arrangement (105) comprises an input (107), an output (209), and a short circuit-limiting element (205, 211). The inventive circuit arrangement (105) is configured so as to transmit a useful signal from the input (107) to the output (209) along a useful signal path, the input (107) and the output (209) being galvanically separated from each other. The short circuit-limiting element (205, 211) is disposed outside the useful signal path.
