SILENT KNIGHT SD505-6IB

Product Overview

The SD505-6IB Silent Knight Line Isolator Module is designed to protect the integrity of an SLC loop by isolating short circuit wiring faults in both Class A (Style 7) and Class B (Style 4) configurations. Without an isolator, a single short could disable the entire loop; however, with the SD505-6IB installed, the system reports a trouble condition while allowing all remaining SLC devices to continue operating normally.

Engineered for fast installation, the SD505-6IB mounts directly beneath the SD505-6AB detector base, providing a compact and discreet solution for enhanced circuit protection.
