Overview
The Atlas Copco Elektronikon Mk5 I/O34 Expansion Module for Atlas Copco Air Compressor (part number 1900520046) adds analogue/digital I/O channels to the Elektronikon controller. It is a control-system component that works together with the Elektronikon controller rather than replacing the whole panel.
Common failure signs include no display, a controller stuck on boot, erratic readings, or the machine refusing to start or load. New, original and function-tested, this 1900520046 is a direct replacement for the original unit.
