Abstract: An input/output module for a data bus includes an insulating housing that is secured on a support rail, with the housing being provided with terminals to receive wires of the bus at side-by-side positions on a surface of the housing. The housing is mounted so that it can swivel with respect to a supporting rail. A printed circuit board can be inserted like a drawer into the housing, and once the printed circuit board is completely inserted, the electronic components on the printed circuit board are electrically connected to the bus.

Abstract: An electrical terminal strip for potential multiplication includes an insulating terminal housing having a plurality of openings arranged in a row. A comb yoke extends in a direction of the row, and is located within the terminal housing. At least one terminal contact row is located in the insulating terminal housing, and includes a plurality of contact connections disposed side by side in the direction of the row. Each contact connection includes a conductor terminal element having a receiving space therein. Each receiving space is in registration With a respective terminal housing opening, and extends in a direction approximately perpendicular to the direction of the row. The receiving spaces receive respective protective conductors inserted from an outside of the terminal housing and through the respective terminal housing opening. Each contact connection further includes a conductor protecting element inserted into the respective receiving space.
