ABB 500SCM01 is signal conditioning module for REB500 busbar protection system, responsible for signal filtering, isolation and time‑synchronization signal processing, widely used for substation relay protection spare replacement parts.

Product Overview

ABB 500SCM01 with part numbers 1MRB200059C and 1MRB15004R0001 is a dedicated signal conditioning module for ABB REB500 busbar protection system. It realizes signal filtering, surge suppression and galvanic isolation for external auxiliary signals and time‑synchronization signals input to the protection rack. It converts field signals into stable signals that can be identified by CPU unit, effectively suppresses high‑frequency interference and lightning surge from substation field wiring. It supports time synchronization signal access, ensures time consistency of fault recording and event log for the whole set of protection equipment. Conformal coated circuit board, rack plug‑in structure, it is an important spare hardware for high‑voltage busbar protection equipment.

Key Features
