ABB PP835A 3BSE042234R2 is a 6.5-inch Panel 800 operator panel with a 640 × 480 TFT color display and resistive touch interface. ABB documents LED backlighting, 24 V DC operation, serial, Ethernet and USB connectivity for the Panel 800 hardware. Confirm the complete article number, installed project, communication settings and panel cut-out before replacement.
PP835A 3BSE042234R2 is a Panel 800 5.1 operator panel for presenting process values, alarms and configured control screens. The actual operation is determined by the loaded HMI project and communication drivers.
Important Notice: Confirm the complete model, revision and installed system before replacement.
PP835A uses a 6.5-inch 640 × 480 TFT-LCD with resistive touch. Check the screen project, touch calibration, backlight condition and the required operator access before returning the station to service.
Record the RS232C, RS422/RS485, Ethernet and USB use on the installed panel. Restore the correct driver, address and network settings from the approved application backup before commissioning.
Back up the PP835A application and record the nameplate, port connections and cabinet mounting before removal. After installation, verify 24 V DC power, communications, touch response, alarms and commanded actions with the machine in a safe state.
Engineering check: Confirm PP835A uses the documented 6.5-inch TFT-LCD panel at 640 × 480 resolution. Inspect the cut-out, gasket and mounting pressure, then calibrate the resistive touch surface across all screen corners.
Acceptance test: Match each configured communication port to the restored Panel 800 project, test data exchange with the controller, and verify USB service access. Confirm the LED backlight is uniform and the panel restarts without project or communication alarms.
PP835A 3BSE042234R2 belongs to the earlier Panel 800 5.1 generation. ABB documentation verifies its hardware specification, while current supply and any migration replacement must be confirmed against the installed HMI project and controller protocol. Moore Automated provides high-quality ABB operator panels and replacement spares matched to the exact application, helping restore the operator station and reduce process downtime.
