B&R 4XP0000.00-K43 X2X Link Operator Keypad Module

Technical Overview

The B&R 4XP0000.00-K43 (4XP0000.00-K43) is a ruggedized, field-level X2X Link keyboard interface module engineered for direct machine interaction and safety integration. Developed for high-visibility deployment in material handling conveyors, automotive stamping cells, and industrial food processing plants, this high-integrity HMI component provides immediate tactile control and emergency override capabilities to eliminate operator latency and prevent critical mechanical asset damage. The unit integrates 6 high-visibility, multi-colored B&R illuminated ring keys alongside a dedicated physical Emergency Stop button, housed within a robust metal frame with a clean white aluminum front foil overlay. Operating natively as an X2X Link slave node, this interface distributes real-time button actuation telemetry and localized LED states across distances up to 100 m between stations, ensuring immediate control availability on expansive factory floors.

Technical Configuration

The electrical architecture and ergonomic field layout of this keypad module focus on high-reliability control room feedback and physical durability:

• Premium Tactile Switch Interfaces: Equipped with industrial Rafix 22FS+ series switch mechanisms featuring robust mechanical travel and highly predictable feedback profiles.

• Variable Multicolored LED Arrays: The 6 round illuminated ring keys feature distinct, independent internal color matrices to reflect varied machine operating conditions:

• 2 Rings: Full spectrum configuration (Red, Yellow, Green, White).

• 3 Rings: Standard status configuration (Red, Yellow, Green).

• 1 Ring: Special function configuration (Red, Yellow, Green, Blue).

• Dual-Contact Emergency Safety: The integrated E-stop button features two independent, hardwired Normally Closed (NC) contacts operating on an isolated 24 VDC control loop for direct integration into safety relays.

• Severe Environment Protection: The front face is sealed with a naturally anodized aluminum frame and polyester foil overlay, securing NEMA 250 Type 4X and IP65 protection against dust, chemical mist, and high-pressure hose water.

Industrial Application FAQs

• How should the 20 A inrush current profile impact the upstream power distribution design?

  The internal power supply circuit of the 4XP0000.00-K43 pulls a brief, intense inrush current spike up to 20 A for less than 1 ms during a cold boot power-up sequence. Upstream 24 VDC switch-mode power supplies (SMPS) or electronic circuit protectors must feature adequate overload capacity or appropriate tripping characteristics to handle this transient spike without dropping the voltage rail.

• Can the 6 illuminated ring keys be driven directly by the user application program?

  Yes. The multi-colored LEDs embedded within the Rafix 22FS+ ring keys are completely mapped to the digital output process image of the B&R master controller via the X2X Link bus. Field engineers can write application logic in B&R Automation Studio to dynamically change key colors (e.g., green for ready, flashing yellow for warning, red for fault) based on automated process steps.

• Is the X2X Link communication line inside this module electrically isolated?

  No. The module does not feature internal galvanic isolation for the X2X Link data lines. Ensure that the entire network share a common reference potential. When routing the 100 m bus lines across different factory zones, use shielded cables and proper ground bonding plates to counteract electromagnetic interference and ground potential differentials.

Field Engineering and Installation Directives

SAFETY LOOP COMPLIANCE: The physical Emergency Stop switch must be tested for mechanical operation and contact continuity weekly. The dual Normally Closed (NC) safety contacts must be routed directly to an approved safety evaluation relay or safety PLC, completely independent of the standard X2X Link data bus processing loop.

Panel Cutout and Gasket Seating Guide

Prepare a precise rectangular panel cutout according to the 170 mm x 80 mm dimensions. Before inserting the unit, inspect the flat neoprene sealing gasket around the inner display front for proper alignment and ensure it is entirely free of particulate debris. Insert the keypad assembly from the front of the console plate and tighten the rear retention clamps progressively to compress the gasket evenly. This step is critical to maintain the NEMA Type 4X and IP65 wash-down seal and prevent liquid entry into the internal electronics.

Multipoint Bus Wiring and Grounding

Terminate the incoming field connection via the integrated 8-pin male multipoint connector. Ensure the cable shield braid from the X2X Link network is stripped correctly and clamped firmly to the metal enclosure frame or the local cabinet functional ground (FE) rail. Keep the 24 VDC power and X2X communication signals separated from high-amperage AC contactor lines and variable frequency drive (VFD) motor output conductors inside the enclosure wire ducts to maximize signal fidelity.
