Product Description:

The 5AC800.CON1-00 add-on module is produced by B & R Automation and belongs to the 5AC CNC Add-on Modules series. Designed for CNC control racks, the unit serves as an interface enclosure where supplemental wiring such as emergency-stop lines can be terminated in a mechanically protected environment. Its aluminum housing and compact profile allow it to fit alongside existing controllers without occupying excessive panel depth, supporting orderly integration of ancillary safety and I/O components in industrial automation systems.

Physically, the enclosure stands only 25 mm high, so it can slide beneath cable ducts or ventilation paths within a cabinet. The front and rear faces are 67 mm wide, while the overall length is 185 mm, giving the unit a slender rectangular footprint that eases side-by-side mounting with other 5AC modules. A mass of just 300 g reduces loading on DIN rails and minimizes vibration stress during machine acceleration. The shell is die-cast from aluminum (ADC12), an alloy that offers moderate strength while conducting heat away from embedded electronics. Internally, the circuit path for the emergency-stop chain is limited to a maximum loop resistance of 1 Ω, helping the safety relay detect wire breaks without nuisance trips.

The exterior finish is a silver metallic semi-flat coating that matches adjoining 5AC panels and resists fingertip smudges. Because the housing follows a straight design profile without recessed contours, cable harnesses can be routed flush along its sides. To keep dust away from internal contacts, the cover seats against a foam perimeter seal that compresses evenly along the mating flange. The sealed cover also helps limit the entry of dust and fluid mist inside the enclosure during routine cabinet operation near machining zones.
