A terminal block electrically relays inside and outside of a partition wall sealing a liquid. The terminal block includes a housing disposed so as to penetrate the partition wall, a bus bar inserted into the housing, a seal member attached to the housing so as to seal a gap between the bus bar and the housing, and a holder assembled to the housing outside the partition wall with respect to the seal member so as to prevent the seal member from coming off. The bus bar extends across the inside and outside of the partition wall through a first through hole of the housing, a seal hole of the seal member, and a second through hole of the holder. Durability of a material constituting the housing to the liquid is better than durability of a material constituting the holder to the liquid.

A modular electrical bus system for a valve manifold has a communication module, a valve driver module, and a plurality of I/O modules each having a plurality of I/O fittings being both electrically and mechanically connectable together via a bridge member connecting adjacent modules. The bridge member has a housing with an interior for housing electronic components for memory storage or Wi-fi reception and transmission that is operably connected to a complementary electrical fitting constructed to be connected to an electrical fitting of a module of said electrical fieldbus system without adding extra length to said bank of modules of said electrical fieldbus system.

A terminal strip for latching onto a mounting rail includes a terminal housing that has a first connection side and a second connection side and a busbar arranged in the terminal housing. At least two conductor connection elements are arranged in the terminal housing. The conductor connection elements each connect at least one conductor to the busbar. Each conductor connection element has a first function shaft having at least one plug-in connection receiving region and at least a second function shaft having at least one screw-connection receiving region arranged on each of the two connection sides of the terminal housing. One connection region is formed for each plug-connection receiving region and for each screw-connection receiving region in the busbar. The function shafts of one connection side are arranged in a manner spaced apart from one another.

Modular switchboard terminal block (10,20) for transmission of data signals (2) is provided, comprising a container (10a,20a) having, arranged inside it, a printed circuit (30) for processing the data signals, which has two opposite sides (30a,30b) in a transverse direction (Y-Y); connectors (11;21) for electrical connection to controlled/detection devices; and a rear end face provided with hook and spring means for mounting on a DIN switchboard rail (6).

An electrical apparatus includes a top-hat rail mount and a first conductor connection with a clamping point. A conductor can be secured via the clamping point. The electrical apparatus can be connected to a top-hat rail via a rotational movement about a rotational axis at the top-hat rail mount. In an embodiment, the first conductor connection be embodied and arranged in such a way that in the state in which the apparatus is connected to the top-hat rail via its top-hat rail mount, the longitudinal axis of a straight conductor which is accommodated in the first conductor connection is located essentially perpendicularly with respect to a straight line which is oriented orthogonally with respect to the rotational axis and which intersects the rotational axis and the clamping point.

A conductor rail module for distributing and a corresponding connection module for tapping a direct current distributed along a mounting rail is described. The connection module comprises a housing whose electrically insulating rear section is connected or connectable to the mounting rail in a form-fit manner.
