| 摘要 |
A device for open-loop control or closed-loop control of a technical installation has a first backplane module, a second backplane module and a third backplane module which are configured to be positioned side by side on a mounting rail in a longitudinal direction. The first backplane module has a first main body and a first contact part. The second backplane module has a second main body and a second contact part. The third backplane module has a third main body and a third contact part. The main bodies each have an upper side comprising insertion openings which are configured to receive electrical contacts of separate electronic modules. The contact parts form a bus line in the longitudinal direction such that plugged-in electronic modules can be electrically coupled to one another by means of the contact parts. The second main body further has a receptacle, in which the second contact part is arranged in one of at least two defined variants. In a first variant, the second contact part has an electrically conductive connection to the first contact part and to the third contact part. In a second variant, the second contact part has an electrically conductive connection to the third contact part, but not to the first contact part. |

1. A device for open-loop control or closed-loop control of a technical installation, comprising:
a first backplane module, a second backplane module and a third backplane module configured to be positioned side by side on a mounting rail that defines a longitudinal direction, wherein the first backplane module comprises a first main body and a first contact part, wherein the second backplane module comprises a second main body and a second contact part, wherein the third backplane module comprises a third main body and a third contact part, wherein the first, second and third main bodies each have an upper side comprising insertion openings configured to receive electrical contacts of separate electronic modules, wherein the first, second and third contact parts are configured to form an electrically conductive bus line in the longitudinal direction, wherein the second main body comprises a receptacle for the second contact part and the second contact part is configured to be arranged in said receptacle in either a first positional arrangement or in a second positional arrangement, wherein the second contact part has an electrically conductive connection to the first contact part and to the third contact part in the first positional arrangement, and wherein the second contact part has an electrically conductive connection to the third contact part but not to the first contact part in the second positional arrangement, thereby allowing to selectively connect or disconnect said bus line at said second backplane module. |
