KJ4001X1-JA1 12P1832X022 Emerson Fisher Rosemount SLS Termination Module

Product Overview

The Emerson KJ4001X1-JA1 12P1832X022 serves as a high-integrity redundant SLS (Safety Logic Solver) terminal block within the DeltaV™ M-series I/O subsystem. This critical interface component facilitates secure field wiring and redundant signal routing for safety-instrumented systems.

Product Description

The KJ4001X1-JA1 12P1832X022 terminal block provides the essential physical termination point for redundant Safety Logic Solvers in the Emerson DeltaV environment. This module supports the dual cable extender architecture, allowing for robust connectivity across distributed control network nodes. By enabling redundant hardware paths, the block ensures that process data remains accessible even if a primary cable or connection fails.

This terminal block features a ruggedized design capable of withstanding extreme thermal stressors ranging from -40°C to +70°C. Furthermore, the unit manages power distribution with a rated capacity of 8 A at 12 VDC, providing high stability against industrial voltage transients. Because the module utilizes high-grade materials, it offers long-term resistance to the corrosive atmospheres often found in chemical processing and oil and gas facilities.

Installation remains efficient due to the compact 16.6 cm footprint, which optimizes space within high-density marshalling cabinets. Although the 12P1832X022 officially entered discontinued status in late 2018, it remains an indispensable legacy component for maintaining the operational integrity of existing DeltaV M-series installations. The block integrates natively with Fisher Rosemount hardware, ensuring that field signals interface correctly with the safety logic layer without signal degradation.
