The Emerson KJ2231X1-EE1 is a SIS Current Limiter for the DeltaV Safety Instrumented System. It provides current-limiting protection for safety-related output circuits in hazardous areas, with an input of 29 VDC and output rating of 28.7 VDC / 120 mA, and is certified for use in Zone 2 / Class I Div. 2 environments.

The Emerson KJ2231X1-EC1 is an End of Line (EOL) Resistance Module for the DeltaV Safety Instrumented System (SIS). It provides a fixed termination resistance at the end of safety loops, enabling the system to detect open circuits and short circuits for loop integrity monitoring. The module requires no calibration and operates on 12 VDC.
