1606-XL120DR Allen-Bradley

1606-XL120DR Allen-Bradley I / O module

Product  Description：

The 1606-XL120DR belongs to the Performance family of Allen-Bradley power supplies. It is engineered to convert AC or DC input voltage into a stabilized DC output. The "DR" designation typically indicates a "Redundancy" capability or specific design features optimized for high-reliability environments. This unit is housed in a rugged metal casing designed to withstand the rigors of industrial cabinets while providing excellent heat dissipation through natural convection.

Product Parameters

The technical specifications of the 1606-XL120DR ensure compatibility with standard industrial electrical architectures:

• Input Voltage: Wide range input supporting $100-120 \text{ V AC}$ or $220-240 \text{ V AC}$ (Auto-select or switch-selectable depending on the specific revision).

• Output Voltage: $24 \text{ V DC}$ (Typically adjustable from $24$ to $28 \text{ V DC}$ via a front-mounted potentiometer).

• Output Current: $5 \text{ A}$ at $24 \text{ V DC}$ or $4.3 \text{ A}$ at $28 \text{ V DC}$.

• Output Power: $120 \text{ W}$ total continuous power.

• Efficiency: High efficiency rating, often exceeding $90\%$, which minimizes heat generation inside the control panel.

• Mounting: Standard $35 \text{ mm}$ DIN-rail mounting.

• Dimensions: Compact width to save valuable rail space in crowded enclosures.

• Status Indicators: Front-facing LED (usually green) indicating "DC OK".

Product Advantages

• Reliability and Longevity: Built with high-quality industrial components, it boasts a long Mean Time Between Failures (MTBF), reducing system downtime.

• Compact Design: The slim profile allows for high power density, enabling engineers to fit more components into a smaller cabinet space.

• Stable Output: Advanced regulation circuitry ensures that the $24 \text{ V DC}$ output remains stable even during input voltage fluctuations or sudden load changes.

• Overload Protection: Equipped with intelligent power management that protects against short circuits and overloads, often featuring a "Hiccup" mode or constant current limiting.

• Easy Installation: The snap-on DIN-rail mechanism and accessible screw terminals simplify the installation and wiring process for technicians.

Important Considerations and Precautions

• De-rating for Temperature: When operating in ambient temperatures above $60\text{°C}$, the output power must be de-rated according to the manufacturer's thermal curves to prevent overheating.

• Ventilation Space: To ensure proper cooling by natural convection, maintain a minimum clearance (typically $40 \text{ mm}$ above and below, and $5 \text{ mm}$ on the sides) between the power supply and adjacent devices.

• Proper Grounding: Ensure the Protective Earth (PE) terminal is securely connected to the system ground to prevent electrical noise issues and ensure operator safety.

• Input Fusing: While many units have internal fuses, it is standard practice to install an external circuit breaker or fuse on the AC input side to protect the cabling.

• Voltage Adjustment: When adjusting the output voltage above $24 \text{ V DC}$, ensure that the total wattage does not exceed $120 \text{ W}$ to avoid tripping the internal protection.

Product Applications

The 1606-XL120DR is a versatile power source used across various automation sectors:

• Programmable Logic Controllers (PLCs): Providing the primary power for Allen-Bradley ControlLogix, CompactLogix, or Micro800 systems.

• Human Machine Interfaces (HMIs): Powering touchscreens and operator interface terminals on the factory floor.

• Sensor Networks: Supplying clean DC power to proximity sensors, photoelectric eyes, and pressure transducers.

• Motor Control: Driving the coils for contactors, relays, and small DC solenoid valves.

• Safety Systems: Powering safety relays and light curtains where a stable and "OK" monitored voltage is critical for machine guarding.
