This Mk5-generation unit is one of the most widely fitted Atlas Copco control platforms, so an exact-match replacement gets a machine back in service quickly. It is fitted to GA37/GA55.
Typical reasons to replace it are a blank or frozen display, a controller that won't power up, an unresponsive keypad, or repeated communication / sensor faults. New, original and function-tested, this 1900520001 is a direct replacement for the original unit.
