Product
The ABB MB21 is an industrially hardened adapter and data-routing module developed for legacy distributed control systems (DCS). Acting as a critical physical and electronic bridge, it slots directly into the localized subrack carrier backplane to interface or adapt signaling paths between peripheral field hardware, input/output clusters, and core processing cards. The unit is designed with robust solid-state electronics and integrated industrial shielding to block out severe factory floor electromagnetic interference (EMI), ensuring steady data synchronization across time-critical process loops without risk of signal latency.
