Abstract: Process control instruments having local intrinsic safety barriers and methods of manufacturing the same are disclosed. An example field instrument for a process control assembly includes a non-protection compartment, intrinsically safe circuitry positioned in the non-protection compartment, a protection compartment, non-intrinsically safe circuitry positioned in the protection compartment, and local barrier circuitry positioned in the protection compartment to operatively couple the non-intrinsically safe circuitry to the intrinsically safe circuitry, the local barrier circuitry to prevent the intrinsically safe circuitry from receiving an electrical energy that is greater than an electrical energy threshold from the non-intrinsically safe circuitry.

Abstract: Embodiments include techniques for automatically restarting a voltage foldback circuit, the techniques include operating a circuit, and detecting a condition of the circuit. The techniques also include performing a foldback operation based at least in part on the condition of the circuit, subsequently detecting the condition of the circuit. The techniques include initiating a timer of the circuit based at least in part on the subsequent detection of the circuit, and returning the circuit to normal operation based on the timer.

Abstract: An electronic circuit (1) for charging a battery (15) of a blower filter device (20), which blower filter device (20) can be supplied with power from an external electric power source. The electronic circuit charging terminals for connection to poles of the battery via electric lines. A measuring device measures a charging current. A control unit receives a measured signal of the measuring device and monitors a flow of current through the lines and switches the circuit component to high resistance or opens the circuit in the absence of a charging current. A battery (15) of a blower filter device (20) is also provided as well as a blower filter device (20) for a blower filter system (30) as well as a method for charging a battery (15) of a blower filter device (20).

Abstract: A method of establishing current limits for each of a plurality of device couplers mounted on a trunk of an electrical circuit at distributed physical positions, in which each of said device couplers is capable of servicing one or more spurs connected thereto, and in which said trunk has a total trunk current and a known resistive component, comprising the steps of: a) establishing physical characteristics of the electrical circuit including i) an order in which said device couplers are mounted on said trunk along its length; ii) a load current each device coupler requires to service the one or more spurs connected thereto; and, iii) a voltage drop of each of said sections of trunk caused by the resistive component thereof, which is proportional to a physical length thereof and the combined load currents of each device coupler serviced by that section of trunk; b) calculating a current limit for each device coupler, which current limit is greater than said load current, according to a predetermined tolerance rationale; c) calculating an intermediate trunk current available to each device coupler by deducting from said total trunk current the current limits of each device coupler preceding that device coupler in said order, as well as a consequential reduction in current caused by said voltage drop of each of said sections of trunk preceding that device coupler; and, d) adjusting said current limits so none exceeds the intermediate trunk current available to the corresponding device coupler.
