Product Overview
The Emerson KJ2003X1-PW1 Redundant SLS Terminal Block is a terminal interface component used in Emerson DeltaV control-system installations. Its function is centered on providing an organized electrical connection point for the associated system wiring and redundant signal or supply arrangement.
Unlike a DeltaV controller or I/O module, the KJ2003X1-PW1 does not execute control logic or process field signals. It belongs to the system interconnection layer, where reliable termination and orderly wiring are important for maintaining the connection between control-system hardware and external circuits.
A simplified arrangement can be represented as:
DeltaV Hardware → KJ2003X1-PW1 → External Wiring / System Circuit
The redundant configuration makes this type of terminal hardware particularly relevant to control architectures where continuity and organized connection paths are important.

Working Principle
The KJ2003X1-PW1 works as an electrical termination interface between the associated DeltaV hardware and external wiring.
The basic connection path can be understood as:
System Hardware → Terminal Interface → Field / External Circuit
Instead of routing every external connection directly through the main control hardware, a terminal block provides a structured point for wiring termination.
In a redundant architecture, the terminal arrangement can accommodate the corresponding redundant connection scheme. This helps keep wiring organized and makes individual circuits easier to identify during commissioning or maintenance.
The terminal block itself does not make control decisions. The connected controller or I/O equipment performs the actual control or signal-processing functions.
Role in a DeltaV Control Cabinet
The KJ2003X1-PW1 belongs to the wiring and interconnection layer of a DeltaV system.
A simplified cabinet structure can be viewed as:
Power Supply → Controller / I/O → Terminal Interface → External Equipment
Each layer has a different responsibility:
| Layer | Typical Function |
|---|---|
| Power | Supplies control-system hardware |
| Controller | Executes control strategy |
| I/O | Exchanges signals with the process |
| Terminal Interface | Provides organized wiring termination |
| Field Equipment | Measures or controls the process |
This arrangement makes the terminal block especially useful when the cabinet contains a large number of connections that need to be clearly separated and maintained.
Redundant Connection Arrangement
Redundancy is commonly introduced into control systems where loss of a single connection or system component could affect plant operation.
The KJ2003X1-PW1 is identified as a Redundant SLS Terminal Block, so its application should be considered together with the corresponding redundant DeltaV hardware and wiring arrangement.
When designing such a system, engineers should verify:
- Redundancy architecture
- Associated controller or I/O hardware
- Terminal assignments
- Wiring topology
- Power distribution
- Cable identification
- Maintenance access
- System diagnostics
The terminal block should be treated as part of the complete redundant architecture rather than as an independent component.
Industrial Applications
The KJ2003X1-PW1 can be used in industrial control installations where organized and redundant system connections are required.
| Application | Typical Role |
|---|---|
| Oil & Gas | Control-system wiring termination |
| Chemical Processing | DeltaV cabinet interconnection |
| Refining | Redundant control-system wiring |
| Power Generation | Control-system connection management |
| Water Treatment | Automation cabinet wiring |
| Pharmaceutical Plants | Organized control-system termination |
| Process Manufacturing | I/O and system interconnection |
| Plant Expansion | Additional system connections |
| Control Cabinet Upgrades | Wiring-interface replacement |
| System Maintenance | Terminal block replacement |
Installation and Maintenance
Before installing or replacing the KJ2003X1-PW1, the associated wiring diagram and DeltaV system configuration should be reviewed.
Recommended checks include:
- Confirm the complete KJ2003X1-PW1 model.
- Identify the associated DeltaV hardware.
- Verify terminal assignments.
- Check redundant wiring paths.
- Inspect cable labels.
- Check terminal connections for looseness.
- Inspect connectors and wiring for damage.
- Verify cabinet wiring against the approved drawings.
- Check system operation after installation.
When replacing a terminal block, documenting the existing wiring before disconnection can help prevent incorrect reconnection.
After installation, each relevant connection should be checked before the associated control-system equipment is returned to normal operation.
