Product Overview
The Allen Bradley 1606-XLP90E-2 Power Supply is a compact industrial power supply used to convert incoming electrical power into a regulated DC supply for control-system components.
In an automation cabinet, a power supply such as the 1606-XLP90E-2 typically sits between the plant electrical supply and devices such as PLCs, I/O modules, sensors, relays, communication equipment, and other DC-powered control hardware. Its role is straightforward but critical: the downstream devices need an appropriate DC power source before the control system can operate normally.
The compact form factor makes this type of power supply suitable for control cabinets where DIN-rail space and cabinet layout need to be considered. It can be used in machine control panels, industrial automation cabinets, and distributed control installations where multiple low-voltage DC devices share a common power source.
When troubleshooting a control cabinet, the power supply should be checked early in the diagnostic process. A loss of DC power, poor terminal connection, overloaded output, or abnormal input condition can affect several control devices at the same time.

Product Features
The 1606-XLP90E-2 is intended for control-panel applications where a compact industrial power supply is required for DC-powered automation equipment.
Key characteristics include:
- Allen Bradley 1606-XLP series power supply
- Compact industrial power-supply format
- Suitable for automation control cabinets
- Intended for powering DC control components
- Suitable for PLC and I/O system installations
- Can supply power to field-level control equipment
- Appropriate for machine-control panels
- Compact dimensions for cabinet installation
- Dimensions of 103 × 73 × 75 mm
- Stated weight of 0.36 kg
The actual suitability of the power supply depends on the connected load, input system, required output characteristics, and cabinet installation conditions.
Working Principle
A practical control-panel power arrangement can be viewed as:
AC Input → Power Supply → DC Control Circuit → PLC / I/O / Field Devices
The power supply receives electrical input from the cabinet’s incoming power circuit and converts it into the DC power required by connected automation equipment.
For example, a PLC cabinet may contain a controller, remote I/O, relays, sensors, communication equipment, and other control devices. These components can depend on a common DC power system. If the supply becomes overloaded or its output is interrupted, several apparently unrelated devices may stop communicating or become unavailable at the same time.
This makes the power supply an important diagnostic point. Before replacing PLC modules or communication hardware, technicians often verify input power, DC output, terminal connections, and the total connected load.
Industrial Applications
The 1606-XLP90E-2 is suitable for a range of industrial control and automation installations.
| Application | Typical Use |
|---|---|
| PLC Control Cabinets | Powering control-system components |
| Industrial Automation | DC supply for automation devices |
| Machine Control Panels | Supplying control circuits |
| I/O Systems | Powering I/O-related equipment |
| Sensor Systems | Supplying DC field devices |
| Packaging Machinery | Control cabinet power |
| Material Handling | Power for control equipment |
| Production Lines | Shared DC control power |
The appropriate application depends on the electrical requirements of the connected equipment and the overall cabinet power architecture.
Compatible System Components
The 1606-XLP90E-2 is normally used alongside multiple control-panel components.
| Component | Function |
|---|---|
| 1606-XLP90E-2 | Supplies DC power to the control system |
| PLC | Executes machine-control logic |
| I/O Modules | Interfaces with field devices |
| Sensors | Detect machine or process conditions |
| Relays | Switch or isolate control circuits |
| HMI | Provides operator interface |
| Industrial Network Devices | Handle controller and device communication |
| Terminal Blocks | Distribute electrical connections |
| Circuit Protection | Protects power and control circuits |
| Field Devices | Receive control signals or provide process feedback |
Correct power distribution is important when several devices share the same DC supply. The connected load should be considered as a complete system rather than evaluating each device independently.
Installation and Maintenance
The 1606-XLP90E-2 should be installed in an appropriate industrial control cabinet with suitable wiring, ventilation, and electrical protection.
Before replacing the power supply, identify the incoming circuit and document the outgoing DC connections. This helps prevent wiring errors during maintenance.
Recommended checks include:
- Confirm the complete 1606-XLP90E-2 part number.
- Verify the input power arrangement.
- Check the DC output wiring.
- Inspect input and output terminals.
- Check for loose terminal connections.
- Inspect wiring for overheating or damage.
- Verify the connected load.
- Check cabinet ventilation.
- Inspect nearby components for signs of excessive heat.
- Check circuit protection devices.
- Verify proper grounding.
- Inspect DC distribution wiring.
- Perform controlled power-up after replacement.
If several PLC or I/O devices lose power simultaneously, the power supply and DC distribution circuit should be checked before assuming that multiple control modules have failed independently.

Technical FAQs
What is the role of the 1606-XLP90E-2 in an automation cabinet?
The 1606-XLP90E-2 functions as an industrial power supply for the control system, supplying the DC power required by connected automation and control components.
Why can a power-supply problem cause several PLC devices to fail at the same time?
Multiple control devices may share the same DC power distribution circuit. If the power supply output is interrupted or becomes abnormal, several PLC, I/O, communication, or field devices can be affected simultaneously.
What should be checked if the control cabinet repeatedly loses DC power?
Start with the incoming power, power-supply terminals, DC output, circuit protection, connected load, wiring, and cabinet temperature. Intermittent terminal connections and excessive load can produce symptoms that resemble an internal power-supply failure.
What should be verified before replacing a 1606-XLP90E-2?
Confirm the complete part number and compare the required input and DC output characteristics with the existing installation. The connected load, wiring arrangement, protection devices, mounting space, and cabinet conditions should also be checked before commissioning the replacement.
