Product Description:

The 7BP704.0 is a modular rack assembly manufactured by B&R Automation for the System 2003 Controllers series. The component serves as the mechanical and electrical backbone for CPU, power supply, and fieldbus modules in a single rail segment, so the controller stack can be installed quickly in an automation cabinet. By grouping logic and I/O elements on one frame, the rack supports neat wiring, orderly module placement, and consistent spacing suited to the dimensional limits common in industrial control panels. This arrangement keeps related control hardware aligned in one accessible location and reduces clutter across the panel interior.

Its overall envelope includes a front width of 314.5 mm, a vertical height of 115 mm, and a housing depth of 23 mm. These dimensions help the rack fit inside shallow cabinets without interfering with door swing or nearby equipment. The controller add-on section contributes an extra 22 mm of lateral space for auxiliary modules, and the carrier is fabricated from Aluminum to keep weight low while helping disperse heat from adjacent electronics. The slim profile also leaves more room for wiring channels and neighboring components in compact cabinet layouts. All fastening points align with a EN 60715 TH35-7.5 mounting rail, allowing direct attachment to the industry-standard top-hat profile used in most switchgear enclosures.

The mechanical layout provides dedicated module positions so power, CPU, and fieldbus interfaces can be arranged on one frame. A threaded strip built into the rack secures each board so vibration does not loosen contacts during machine operation. Clearance is maintained by keeping 30 mm of free space above the rack and 35 mm below it, which supports natural convection and leaves room for cable bends. Left and right side sections are included to cover exposed edges, and the rack has 4 available positions.
