Product Details:

The B&R 4E0021.01-090 is a Panelware membrane keypad module designed for B&R System2005 HMI operator terminals, built with 12 numeric keys plus 3 yellow LED backlit function keys to complete operator input tasks on industrial machines. Operators can use this numeric keypad to input set values, adjust process parameters, acknowledge alarms and trigger machine actions. The function keys support custom legend labels by replacing membrane sheets according to different machine application requirements. It connects to B&R panel controller via dedicated internal interface, transmitting key press signals to the host control unit in real time. Each LED consumes extra 3mA when lit, while the base current consumption is only 1.5mA at 24VDC, achieving low power consumption. Built-in diagnostic circuits continuously monitor key scanning status and communication link condition, feeding fault information back to the B&R PCC system for maintenance scheduling. The blue housing has dimension of 96mm ×96mm ×35mm, adopting standard panel cutout mounting on equipment doors for simple installation and fast spare replacement. The hardware can operate stably within 0℃ to 50℃ working temperature, with relative humidity range from 5% to 95%. The rugged membrane structure can resist dust and slight liquid splashes, and withstand mechanical vibration on workshop equipment. The B&R 4E0021.01-090 works with B&R display panels, panel controller and 2005 PCC hardware to build complete HMI operation systems. It is widely used in packaging machinery, textile equipment, printing production lines and special machine automation, delivering reliable numeric keypad function key operator input and minimizing unexpected downtime of process production equipment.
