Description

NU8976A99, HIER466665R0099, and HIEE320693R0001 are different identifiers for the same type of industrial automation module from ABB (the correspondence between the main model and spare parts/order numbers). They are mainly used in ABB Advant OCS and Symphony DCS distributed control systems. The following is their complete information:

I. Technical Specifications1.
