ABB 1MRK002133-ABr02 - Circuit Board (cross-ref 1MRK000005-520)

The ABB 1MRK002133-ABr02 is a circuit board that specialists list under several functions - binary output module, analog-to-digital module with time synchronization, and control panel board - while also pairing it with the alternate code 1MRK000005-520 for the same physical board of Swedish origin. One page further claims it is an order code within the REF615 feeder protection range, which could not be confirmed against an official ABB source. Because the descriptions conflict, this page does not assert a single function or publish unverified electrical parameters; the exact role should be verified against your removed board. Units are offered new and used with warranty from multiple independent dealers.
