Product Description:

The 4XP0057.00-00W keypad module is produced by B & R Automation and belongs to the 4XP Keypad Modules series. It is a compact operator interface that adds five tactile keys to an X2X network, letting a machine builder place basic start, stop, or mode-select inputs directly on a cabinet door or pendant. When installed, the module functions as an X2X slave node, drawing low-voltage power from the internal bus and relaying user commands to the central PLC without additional I/O wiring.

The front of the unit is sealed to IP65, while the rear carries a separate IP20 rating, so the face can be exposed to washdown or dust but the enclosure interior still needs cabinet protection. Supply is regulated at 24 VDC ±25%, and a brief inrush of 20 A for less than 1 ms is tolerated by the power rail before the circuitry settles to a maximum draw of 0.35 A. An eight-pin male multipoint connector routes this power, the X2X signal pair, and the internal bus supply to the board. Embossed polyester keys sit behind a molded overlay, giving operators a defined actuation point through a durable front surface. The flat-cable bus allows multiple 4XP modules to be daisy-chained across large machines without repeaters.

Mechanical clearance is simplified by a width of 172 mm, a height of 52 mm, and a depth of 40.4 mm, keeping the keypad flush to a panel with minimal intrusion into the cabinet. Weighing only 134 g, the assembly adds negligible load to light-gauge doors. A maximum station distance of 100 m supports decentralized layouts where the keypad must follow moving gantries or conveyors yet remain inside the guaranteed timing budget of the X2X bus. Polyester overlay material resists oils and cleaning agents, preserving legibility throughout the service life.
