Abstract: An automation device has a main module and an interchangeable connection module in which a fieldbus port of the automation device is located. The automation device is characterized in that the interchangeable connection module contains a non-volatile memory which can be read out by the main module of the automation device. A method for operating the automation device includes the steps of connecting a main module of the automation device with a connection module, reading the non-volatile memory of the connection module, detecting any incompatibilities between the main module and the connection module, and placing the automation device in operation if no incompatibilities are detected.

Abstract: A module latching arrangement for mounting and dismounting on a generally U-shaped support rail at least two module base bodies arranged orthogonally above and extending transversely across the support rail, each of the base bodies having a pair of bottom corner portions arranged on opposite sides of the support rail. At least one foot member is connected for horizontal longitudinal sliding movement relative to one of the base body corner portions relative to the adjacent support rail horizontal flange portion. A lateral displacement arrangement on the foot member is operable, when the foot member is displaced from a locked position toward an unlocked position relative to the support rail, to displace the first base body laterally away from an adjacent second base body mounted on the support rail. The foot member is latched in either a locked or an unlocked position relative to the base member.

Abstract: An electrical module includes a rectangular carrier frame adapted for vertical transverse mounting on a horizontal support rail, a housing for mounting an electrical component in an open-top chamber contained in the carrier frame, and a rectangular electrical connector mounted on and extending across the upper end of the carrier frame, thereby to enclose the component and afford electrical connection with upper terminals thereof. The connector is pivotally connected at one end with the carrier frame for displacement between open and closed positions, and a fastener device serves to lock the connector in the closed position to the carrier frame. Alternatively, the ends of the connector are removably fastened to the carrier frame. Lower terminals of the component are connected with lower contacts arranged at the bottom of the chamber for connection with corresponding lower contacts of adjacent modules mounted in stacked relation on the support rail.

Abstract: An electrical contact arrangement includes a planar conductive metal blank having sections that are foldable to define pairs of orthogonally arranged component contacts and bus blade contacts. Connected with a first pair of opposed side edges of a horizontal rectangular core section of the blank are a pair of rectangular component contact sections that are upwardly bent to define a pair of component contacts for receiving therebetween an electrical component, such as a printed circuit board. Connected with the orthogonally arranged second pair of opposed side edges of the core section are a pair of rectangular support sections that are bent downwardly, whereby a corresponding pair of bus blade contact sections connected with corresponding edges of the support sections extend in vertical parallel spaced relation to define a pair of bus blade contacts adapted for insertion between the downwardly bent support sections of a corresponding second electrical contact arrangement.
