Product Description:

B&R Automation’s 4XP0000.EX-K64 belongs to the 4XP Keypad Modules series. It serves as an operator interface element in decentralized machine control. Mounted on a cabinet door or panel, it allows users to issue commands and acknowledge machine states through its ring-style keys while communicating with the main controller over the X2X real-time fieldbus used on large equipment lines. This arrangement supports simple local input at distributed machine stations where direct command access is needed.

The module measures 77 mm in width and 123 mm in height, while its front projection remains at 52.6 mm, allowing installation in shallow enclosures. It weighs 200 g, and the front foil and gasket meet the IP65 rating, so sprayed water and dust cannot reach the internal electronics. Electrical supply is nominally 24 VDC; at that voltage, the internal circuitry draws up to 320 mA, which equates to a worst-case demand of 8 W. An internal bus supply is present, meaning the node forwards power for neighboring I/O modules on the same rail. The device registers on the network as an X2X slave, so all key events and status data are transferred over deterministic bus cycles for timely exchange with the control system.

For operator interaction, the keypad carries 6 ring keys whose backlit legends can be assigned to machine functions. B&R specifies a maximum X2X station distance of 100 m between this unit and the preceding node, which permits remote installation on large production lines without repeaters. Power enters through a 4-pin M8 connector, while bus communication uses a separate 4-pin M12 connector, so the power and network interfaces remain clearly separated. The electronics remain functional up to 3000 m operating elevation, so the module can be used in most industrial facilities without altitude-related limitations.
