Abstract: A field bus connection module for coupling a local bus conductor to an associated field bus system includes a housing formed from functionally different, alignable terminal blocks, and spacing elements. The terminal blocks comprise a feed block and a grounded conductor block. Removably connected with the housing is at least one functional printed circuit board. Removal of the functional printed circuit board necessarily interrupts a separable connection between the local bus conductor and the field bus, although the field bus continues to be connected to the functional printed circuit board.

Abstract: A terminal block assembly (1) includes ground (16), power supply (7), and control signal (8) terminal blocks adapted for mounting as a unit on a grounded mounting bar, the assembly including a power distribution terminal section (3), a control signal terminal section (4), a field bus terminal connection section (2), and upon which assembly are mounted an electronics control module (23) and an internal bus bar (5). First control signal block terminals (4a) are connected with electrical components of the system, and second control signal block terminals (4b) are connected with ground via the electronics module. Tapped plug-in connectors (17) afford connection of bridging (12) or termination (18) link devices to the second terminals, thereby to establish the internal configuration of the assembly.

Abstract: In this modular control assembly, individual bus conductor segments are integrated in modular, alignable housing blocks. The bus conductor segments have strip conductors on the upper and lower surfaces thereof. The bus conductor segments of mutually adjoining housing blocks are electrically connected by separating slide contact members. The contact members comprise a closed housing containing upper and lower contact springs for engaging the strip conductors of the bus conductor segment. The slide contact members can be pushed between an extended position in which they grasp the mutually facing ends of bus conductor segments (8) of neighboring housing blocks and a retracted position in which only one bus conductor segment is covered by the slide contact member.
