The B&R 4P0420.00-490 is a Power Panel PP21 operator panel with integrated controller functionality. It is used in older B&R machine control systems where operation, visualization, PLC control, digital I/O and expansion module connection are integrated in one compact panel device.

This model is equipped with a 4 x 20 character black and white LCD display with backlight and 34 membrane function keys. It includes a System 2003 compatible CPU, 700 kB SRAM, 1.4 MB FlashPROM, one PCMCIA slot, one RS232 interface, one electrically isolated CAN interface, six slots for System 2003 screw-in modules, ten 24VDC digital inputs and eight 24VDC digital outputs rated at 0.4A. The unit uses 24VDC supply voltage and provides IP65 front protection when installed correctly.

The 4P0420.00-490 should be described as a Power Panel PP21, operator panel with controller, or integrated machine control panel. It should not be described as a simple power panel only, power distribution unit, servo drive, inverter module, power supply, or standard touch screen HMI. This product combines panel operation and controller functions, so the machine program, memory card, wiring and installed screw-in modules must be considered before replacement.

This Power Panel PP21 is commonly used in packaging machinery, filling equipment, textile machines, printing machines, material handling equipment, small and medium production machines, and older machine control systems using B&R System 2003 architecture. It is often replaced when the display becomes dim, membrane keys fail, the controller no longer starts, communication fails, I/O does not respond, or the original panel is no longer stable.

For replacement applications, the complete model number 4P0420.00-490 must be checked carefully. Similar Power Panel 15, PP21, PP35 and PP41 devices may have different display types, keypad layouts, controller memory, fieldbus interfaces, I/O configurations, expansion slots, terminal block requirements and machine software. Please do not replace the panel only by appearance or by the Power Panel name.

Before ordering, please confirm the original panel label, display type, keypad layout, PCMCIA memory card, machine software backup, RS232 wiring, CAN wiring, digital I/O wiring, terminal block type, installed screw-in modules and cabinet installation size. TB712 terminal blocks are ordered separately, so please check whether the old terminal blocks can be reused or whether new terminal blocks are required.
