Data bus input output module

摘要

The input/output modules for a data bus can be locked next to each other on a carrier rail (6). Each module includes a basic terminal block (4,5). The blocks have several adjacent, spaced apart connection planes with clamp points for the parallel wiring of a bus user (actuator, sensor, device ) per plane. Each module also has input/output electronics (20) which can be plugged into the basic block (4,5). The electronics (20) connect the bus users with the serial bus lines running through the block (4,5). The terminal block insulating housing has a flat base channel (24) which extends parallel to the rail (6) over the whole width of the block (4,5). A circuit board (25) extending over the whole block is arranged in the channel (24). The circuit board (25) has conductive tracks for the bus lines and for the current supply for the input/output electronics (20) such that the electronics (20) can be plugged into the circuit board (25) from above to contact the tracks. The tracks of neighbouring blocks on the rail (6) are connected to each other by a U-shaped electronic bridge (27).
