Abstract: A controller for an industrial automation system includes a main module having a housing, which can be fitted onto a DIN rail via a base, at least two printed circuit boards arranged in the housing, and a heat sink also arranged in the housing and connected with the base. One of the circuit boards is a backplane bus printed circuit board, which provides a backplane bus, and the other is a main printed circuit board. The heat sink is attached to at least one of the printed circuit board to cool its components.

Abstract: Controller for an industrial automation system, having a main module (1) with a housing, which can be fitted onto a DIN rail by means of a base (10), and with at least two printed circuit boards (20) which can be arranged in the housing, one of these printed circuit boards (20) being a backplane bus printed circuit board (21) and one being a main printed circuit board (23), wherein the main printed circuit board (23) is assigned a heat sink (50) for the cooling of components and wherein the backplane bus printed circuit board (21) provides a backplane bus, wherein the heat sink (50) is arranged in the housing, is attached to the base (10) and supports at least one of the printed circuit boards (20).

Abstract: A terminal strip is formed as a printed circuit board plug connector and has a strip-like housing composed of a plurality of terminal housings which are arranged alongside one another in an arranging direction X. The housings are mechanically connected to one another. The terminal housings each have a plugging face side on which they have at least one first plugging contact which can be plugged together with a corresponding plugging contact of a corresponding plug connector.

Abstract: A terminal block connecting apparatus includes first and second support members displaceable from a disengaged condition toward an engaged condition in which corresponding main terminal blocks are brought into electrical engagement, characterized by the provision of first and second test terminal blocks connected with the support members for electrical engagement when the first and second support members are in an intermediate condition between the disengaged and engaged conditions. One of the test terminal blocks is supported by a carrier member for movement relative to the associated support member, whereby the test terminal blocks will remain in electrical engagement during displacement of the support members between the test and connected conditions. A friction retaining arrangement serves to resist displacement of the carrier member relative to its associated support member.

Abstract: An electrical power distribution device such as a junction box or the like includes a status indicator that also serves not only to indicate the status of energization of a connector mounted in a first housing opening, but also to illuminate a translucent indicia-bearing plate mounted in second housing opening. The housing contains a chamber in which are mounted a light emitting diode that is energized simultaneously with the connector, and a light transmitting member that directs the light produced by the LED toward the second housing opening.
