Panel 800 repair and refurbishment
The ABB Panel 800 (PP846, Panel 800 version 5.1) is a legacy ABB operator panel found in process industries and power generation facilities. Membrane keypads are the most commonly replaced component, with aftermarket replacements available from specialist suppliers. As a legacy product, repair is often the only option for keeping these panels in service without a costly platform migration.

Panel 800 repair FAQs
Can you replace the membrane keypad on a Panel 800?
Yes. Aftermarket membrane keypads are available for the PP846 Panel 800. We source compatible replacements and carry out the swap with functional verification before return.
Is the ABB Panel 800 still supported by ABB?
The Panel 800 v5.1 is a legacy product. Official ABB support is limited, making third-party repair the primary option for keeping these panels in service.
My Panel 800 has multiple intermittent faults — is it worth repairing?
Multiple intermittent faults on a legacy panel often point to widespread capacitor degradation. We will assess the unit and advise honestly — if repair cost approaches the economic threshold, we will recommend alternatives.
