Description
Product Overview
The Emerson KJ2221X1‑BA1 (VS6002, alternate part number 12P3232X132) is a SISNet safety network repeater module for Emerson DeltaV SIS safety instrumented system. It regenerates, isolates and extends the SISNet safety bus communication signals between DeltaV SLS logic solvers and distributed SIS I/O nodes. The repeater boosts signal integrity over long cable runs, isolates network segments to limit fault propagation and expands the maximum distance and node quantity of the SIS safety network. Equipped with LED diagnostic indicators and continuous internal health monitoring, it maintains deterministic safety communication required for ESD, fire & gas and burner management safety loops. This unit has ISA G3 conformal coating for corrosive plant environments and is widely stocked as critical spare in refineries, petrochemical, chemical and power plants.
