Abstract:
A redundant power supply motherboard assembly connects control segments of a fieldbus-type control system to a host computer. The assembly has a compact design with pairs of power supply modules in side-by-side nests on the motherboard. The nests are mounted on the motherboard in desired locations and securely hold the modules on the assembly despite vibrations, shocks and handling to prevent contact impairment. The nests provide touch protection for components on the motherboard.
Abstract:
A voltage limiting device for limiting the voltage being transferred from a trunk circuit to a spur circuit of a distributed control network includes an AC signal device that passes the AC data signals between the trunk circuit and the spur circuit.
Abstract:
A base element and a surge protection system incorporating the base element are provided. The base element includes a housing having a front portion and a rear portion. Apertures in the rear portion provide access to contacts secured within the housing, and a receiving portion extending from the front portion includes at least one receiving section for receiving a surge protection cartridge. Plug receptacles in the receiving portion are in electrical communication with the contacts to incorporate the surge protection device in a circuit when the surge protection cartridge is inserted. The base element is configured to mount orthogonally to a case such that conductors secured to the contacts extend through the apertures and into an enclosure defined by the case in a substantially linear direction. The system includes a case configured to be attached to a rack mount system and a plurality of base elements secured to the case.

Abstract:
FIG. 1 is an exploded front-top-right perspective view of an electrical housing showing our new design. FIG. 2 is an exploded rear-top-right perspective view of the electrical housing shown in FIG. 1. FIG. 3 is a front-top-right perspective view of the electrical housing of FIG. 1, shown with the covers attached. FIG. 4 is a rear-top-right perspective view thereof. FIG. 5 is a front view thereof. FIG. 6 is a top view thereof. FIG. 7 is a rear view thereof. FIG. 8 is a bottom view thereof. FIG. 9 is a right side view thereof; and, FIG. 10 is a left side view thereof. The broken lines in the drawings show portions of the electrical housing that form no part of the claimed design. The dot-dash lines showing the exploded structures in FIGS. 1 and 2 are shown for clarity of disclosure and indicate the path along which the removable covers have been exploded away from the remainder of the electrical housing and form no part of the claimed design.
Abstract:
An enclosure assembly for housing printed circuit boards and related electrical components having a secured faceplate that may be removed by use of a hand tool.
Abstract:
I/O network modules connect field devices to a process control network. Each I/O network module includes a set of electrical connectors for connecting a field device to the module and an I/O channel extending from the set of electrical connectors to a network port. The I/O channel includes a conversion circuit that converts between an I/O signal and network-compatible signals. Each I/O channel connected to the process control network through an I/O network module is associated with its own unique network address. This enables controllers and field devices on the process control network to communicate essentially directly with one another through the network.
