The Emerson KJ2231X1-EC1 is a DeltaV SIS End-of-Line Resistance (EOLR) module designed to ensure field wiring integrity monitoring in safety instrumented systems. It is used to supervise discrete input/output loops by providing a defined resistance at the end of a safety circuit, allowing the system to continuously detect open circuits, short circuits, or wiring faults.
This module is a key part of Emerson’s SIS auxiliary module family, working alongside relay, current limiter, and voltage monitoring modules to support high-integrity safety architectures (SIL-rated systems) in oil & gas, petrochemical, and power generation industries.
