Product Description:

The 5AC800.CON2-00 add-on module belongs to the 5AC CNC Addon Modules series produced by B&R Automation. It mounts beside main control electronics inside CNC enclosures to add interface capacity for motion and safety wiring while keeping the overall equipment footprint compact. This arrangement keeps auxiliary connections close to the control hardware, which helps avoid awkward cable runs in densely packed panels. Its aluminum housing, flat profile, and matched mounting pattern allow the part to line up mechanically with neighboring modules and support an orderly cabinet layout without using excessive panel space.

One mechanical feature is a connector positioned at an angle of 60°, and the slanted exit helps relieve cable bend stress in shallow control cabinets. For the machine-safety circuit, the emergency-stop loop is designed for a maximum resistance of 1 Ω, allowing the safety relay to detect an open or short with predictable accuracy. Keeping this resistance low supports reliable signal transfer through the stop circuit during normal operation. Vertical clearance is limited by the housing height of 25 mm, so multiple modules can be stacked without blocking ventilation paths. The body length of 185 mm provides room for internal conductors and locking tabs, and the shell is pressure-cast from ADC12 aluminum to help move heat away from the internal electronics.

The side profile spans 68.4 mm, leaving consistent air gaps between adjacent cards and allowing service access to terminal screws and nearby wiring points. Despite the die-cast shell, overall mass is only 500 g, which helps limit static load on DIN rails and vibration-isolated mounting plates. Lower weight can also reduce stress on support hardware when the cabinet is exposed to machine vibration. The exterior uses a semi-flat silver metallic coating that adds corrosion resistance and visually matches surrounding hardware in the enclosure. This finish also gives the module a clean, uniform appearance without changing the compact form needed for close side-by-side installation.
