Product Description:
The 4E0031.01-590 is a panel-mounted keypad accessory produced by B&R Automation within the 4E0 PanelWare Accessories series. Designed for installation alongside operator terminals, the module supplies dedicated hardware keys that trigger programmed actions inside a PLC or motion controller. By providing tactile input at the enclosure door, it streamlines routine machine commands and reduces reliance on on-screen soft buttons in industrial automation cells. This arrangement is useful for jog, reset, acknowledgment, and mode-selection tasks that benefit from a physical button press. Because the keys are separate from the display surface, input remains available even when screen menus change during operation.
The keypad draws only 1.5 mA at 24 VDC, so the system power budget stays almost unchanged. That low current demand allows the accessory to operate from the same control supply used by nearby interface hardware without adding a meaningful load. It has 8 function keys, and the controller reads each one as a discrete signal for separate command assignment. A mounting 35 mm depth keeps rear clearance requirements low when cabinets contain densely packed components. The Aluminum housing adds rigidity and helps dissipate heat from the internal LED drivers. Continuous service within a surrounding air temperature of 0 to 50 °C supports operation in most factory environments without added climate control.
A front face of 96 mm height aligns with standard IEC panel grids and simplifies cutout preparation. Operator visibility is enhanced by Yellow key LEDs that indicate active or acknowledged states, even in low-light areas. A single 1 label field lets the machine builder identify the key group with a printed legend instead of separate stickers. The illuminated keys and grouped label area make the control section easier to read during routine operation. During storage or transport, the circuitry tolerates ambient conditions from -20 to 60 °C, allowing normal handling across typical indoor logistics and warehouse conditions.
