Abstract: A system includes a housing of a printed circuit board arranged in the housing and at least one functional element, wherein the housing has at least one exchangeable side surface, wherein openings which correlate to electrical connections of the printed circuit board are provided in the at least one exchangeable side surface, and wherein the functional elements each pass through an opening in the side surface to the electrical connections of the printed circuit board assigned to them and are connected to said connections.

Abstract: A modular arrangement is proposed with modules (10-25) added in a row direction, these being constructed at least partially as valve modules (16-21, 23, 24), wherein one module is constructed as a control module (10) and is connected to the other modules (11-25) by control and/or sensor lines (30) running transversely through these modules. Voltage supply lines (36, 37) powered by a voltage source (33) run transversely through the modules (10-25). At least one module is constructed as a safety module (12) and has a switching arrangement (38) for interrupting the voltage supply lines (36) to the modules (13-21) powered via the safety module (12) in the activated state. Safety-related control and/or diagnostic electronics are provided for activating the switching arrangement (38).

Abstract: A control device for the control of a module battery, comprising a first external bus interface for the reception of external control commands from a higher level control and an internal bus interface for an internal bus, by way of which battery modules connected with the control device are able to be controlled in accordance with the external control command and by way of which the battery modules may transmit messages to the control device. The control device possesses a second external bus interface, by way of which visualizing data for visualizing at least one function of the module battery may be applied.

Abstract: A control device having a base which is provided with one or more component mounting areas. On each component mounting area there is a first electrical central interface connected with an internal electrical bus. On each component mounting area an electrical connection module or an electrically controlled fluid control module may be selectively mounted, which respectively has a second central interface complementary to the first electrical central interface. The fluid control module is provided with a valve means, which is controlled by signals supplied by means of the internal electrical bus. The connection modules are provided with inputs and/or outputs for the connection of electrical cables.

Abstract: A linear drive with a having a housing cover arranged on at least one terminal region. In the housing position detecting means are arranged. At the laterally aligned outer face of the housing cover an electromechanical connection means is provided for detachable connection of an electrical conductor arrangement leading toward the linear drive from the outside to the position detecting means. The electromechanical connection means is accommodated in a completely sunk manner in the housing cover without standing proud of the laterally aligned outer face.

Abstract: An electronic part having electrical terminals for the connection of further equipment includes at least one internal electronic unit, which is connected with the electrical terminals. The electrical terminals are part of an adapter arranged in a replaceable fashion on a base having the internal electronic unit. The adapter possesses a standardized first electrical interface connected with the electrical terminals, which on mounting and dismounting the adapter on and from a standardized second electrical interface connected with the internal electronic unit and mounted on the base, are contacted and put out of contact with the first interface coming into and out of electrical contact with the standardized second electrical interface, which are provided on the base and are connected with the internal electronic unit.
