Description
Product Overview
DCC2380A (Order code:3EST49-156) is the Digital Control Card developed by ABB for the RTU560 Remote Terminal Unit platform.
It functions as a discrete signal processing slave module installed inside RTU560 subrack. The module collects binary status from field contact signals, performs signal filtering and debounce processing, and exchanges data with the 560CMU05 main controller via internal rack bus. It is widely used in power system substation automation for breaker position, protection status and sequence-of-event signal acquisition.
