B&R 4XP0000.00-K40 cHMI 3 Add-on Keypad Module X2X Slave

Product Overview

The B&R 4XP0000.00-K40 (4XP0000.00-K40) is a robust cHMI 3 add-on keypad module designed as an X2X slave device for distributed control architectures. It features four square illuminated ring keys capable of displaying red, green, and yellow colors, providing clear visual status feedback directly at the machine interface. This module is widely deployed in packaging machinery, printing lines, and process skids where operators require tactile control and immediate status indication away from the main HMI panel. The unit connects via an 8-pin male multipoint connector and draws power directly from the internal bus supply, simplifying cabinet wiring. With a front protection rating of IP65 and a metal housing, it withstands harsh industrial environments, including washdown areas and locations with high levels of dust or moisture. The integrated Run and Error LEDs allow for rapid diagnostics without opening the control cabinet, minimizing downtime during commissioning and maintenance.

Interface and Mechanical Integration

The 4XP0000.00-K40 utilizes the B&R X2X Link interface, allowing it to be positioned up to 100 meters away from the master station (such as an X20 bus controller or Automation PC).

•  

  Key Configuration: Equipped with 4 square illuminated ring keys. Each key supports 3 colors (Red, Green, Yellow) and is controlled individually via the X2X protocol, enabling dynamic state indication (e.g., Green for "Ready", Red for "Fault", Yellow for "Active").

   

•  

  Connection: Uses an 8-pin male multipoint connector (variant). The module is powered via the internal bus supply (24 VDC, +/- 25%), eliminating the need for a separate power feed at the mounting location.

   

•  

  Mounting: Designed for front panel mounting. The front bezel is aluminum with a natural anodized finish (Pantone 427 C), while the rear housing is metal. A flat gasket ensures the IP65 seal against the panel cutout.

   

•  

  Required Accessories: Operation requires the separate purchase of the 8-pin terminal block 0TB1108.8110 (cage clamp, 1.5 mm2, vibration-proof screw flange). A 3-pin terminal block (0TB703.81) is typically included for specific wiring variants.

   

Technical Specifications

FAQs

Is the 4XP0000.00-K40 compatible with Automation Studio?

Yes. The module is fully supported in B&R Automation Studio. Hardware upgrades (HWUpgrade) are available for versions V2.6, V3.0, V4.0, and V6.0, ensuring seamless integration into existing projects and I/O mapping configurations.

Does this keypad module require an external power supply?

No. The 4XP0000.00-K40 is powered via the X2X bus internal supply (24 VDC). As long as the X2X master provides the bus power, the keypad operates without additional wiring for power, though the specific 8-pin terminal block (0TB1108.8110) must be ordered separately for the connection.

Can the keys be customized with different labels?

Yes. B&R provides legend strip templates for the 4XP0000.00-K40, allowing users to print custom labels fitting under the polyester panel overlay. This enables application-specific marking (e.g., "Start", "Stop", "Reset", "Jog") to match the machine function.

What is the difference between the -K40 and -K20 versions?

The -K40 version features square illuminated ring keys, whereas the -K20 version typically features round keys. Both offer 3-color illumination and X2X connectivity, but the physical key shape and potentially the front frame design differ to match specific cHMI panel aesthetics.

Panel Mounting and Wiring Instructions

•  

  Mandatory Terminal Block: The 4XP0000.00-K40 does not ship with the connector. You must order the 0TB1108.8110 (8-pin, 1.5 mm2 cage clamp terminal block) separately. Ensure the cable shielding is connected to the metal housing via the cable gland or clamp to maintain EMC compliance.

   

•  

  Panel Cutout: The module requires a precise panel cutout of 90 mm x 80 mm. The supplied flat gasket must be placed between the front frame and the panel to achieve the IP65 rating. Tighten the rear mounting clamps evenly to avoid warping the front frame, which could compromise the seal.

   

•  

  X2X Cable Routing: Since the module acts as an X2X slave, use shielded twisted pair cable for the X2X connection. Keep the distance under 100 m. If daisy-chaining multiple X2X slaves, ensure the termination is set correctly on the last device in the chain according to the X2X topology rules.

   

•  

  Cleaning and Maintenance: The front polyester overlay and aluminum frame tolerate industrial cleaning agents. However, avoid high-pressure direct spraying on the gasket seam. Use soft cloths for cleaning; abrasive pads may damage the anodized finish or scratch the overlay, affecting readability.
