1606-XL60D Industrial Power Supply (60W 24VDC Output)

The 1606-XL60D represents Allen-Bradley's commitment to delivering industrial-grade power solutions for mission-critical automation systems. This 60-watt DIN rail power supply converts wide-range AC input (95-264VAC) into stable 24VDC output, engineered specifically for ControlLogix, PLC-5, and distributed I/O architectures. With 87.5% typical efficiency and 740,000-hour MTBF rating, it solves the persistent challenge of reliable power delivery in harsh industrial environments where voltage fluctuations and thermal stress are constant concerns.

Designed for automation engineers, system integrators, and maintenance teams managing process control systems, this compact unit (49mm width) fits seamlessly into space-constrained control panels. Whether you're powering remote terminal units in oil & gas facilities, HMI panels in pharmaceutical clean rooms, or sensor networks in automotive assembly lines, the 1606-XL60D provides the voltage regulation and protection features demanded by modern industrial operations.

Key differentiators include +105°C rated longlife electrolytic capacitors for extended service life, gradual overload protection that prevents nuisance shutdowns, and >20ms hold-up time to bridge momentary power interruptions. The result: reduced downtime, lower maintenance costs, and peace of mind for 24/7 production environments.

Core Features & Benefits

✓ Wide-Range Universal Input (95-264VAC)
Eliminates voltage selector errors during global deployments. Single SKU supports both 115V and 230V installations, reducing inventory complexity and field wiring mistakes. Accepts 47-63Hz frequency variation for generator-powered sites.

✓ Superior Voltage Regulation (+5%/-1%)
Maintains tight 24VDC output tolerance even under fluctuating line conditions. Critical for precision analog instrumentation and PLC analog input modules requiring stable reference voltage. Reduces calibration drift in process control loops.

✓ Extended MTBF (740,000 Hours at 40°C)
Premium-grade components and conservative thermal design deliver 84+ years theoretical lifespan. Translates to fewer emergency replacements, reduced spare parts inventory, and lower total cost of ownership over 10-15 year equipment lifecycles.

✓ Compact DIN Rail Footprint (49mm Width)
Saves valuable panel real estate—critical in retrofit projects with limited enclosure space. Allows side-by-side mounting of multiple supplies for multi-voltage architectures (24VDC + 5VDC logic power).

✓ Gradual Overload Protection
Unlike hard-cutoff designs, output voltage reduces gradually up to 1.5x rated current before shutdown. Prevents system crashes during motor inrush or solenoid activation transients. Enables graceful degradation rather than catastrophic failure.

✓ Low Ripple & Noise (<25mVpp)
Clean DC output protects sensitive analog circuits and communication modules. Reduces electromagnetic interference in proximity to Ethernet switches, DeviceNet scanners, and wireless access points.

Technical Parameters & Selection Guide

Selection Criteria:

• Calculate total load current: Sum all 24VDC device currents + 20% safety margin
• Verify ambient temperature: Use 1606-XL120D (120W) if panel temp exceeds 55°C
• Check hold-up time requirements: Critical systems may need 1606-XL120DR redundant module
• Consider future expansion: Leave 30-40% capacity headroom for additional I/O modules

Extended Functions

Remote Monitoring Integration
While the 1606-XL60D lacks built-in communication, pair with Allen-Bradley 1606-XLP95E (95W model with DC OK relay) for remote status monitoring via PLC digital inputs. Enables predictive maintenance alerts when output voltage drifts outside tolerance.

Redundant Power Architectures
Combine with 1606-XL120DR redundancy module for N+1 configurations in critical applications. Automatic load sharing and diode-OR switching ensure uninterrupted operation during single-supply failures.

Frequently Asked Questions

Q: What input protection is recommended for the 1606-XL60D power supply?
A: Use a 10A slow-blow fuse (HBC type) or Allen-Bradley 1492-SPU1C100 circuit protector on the AC input. This protects against short circuits while tolerating the 25A inrush current during cold starts.

Q: Can I parallel multiple 1606-XL60D units to increase output capacity?
A: No, this model lacks internal ORing diodes required for safe parallel operation. For loads exceeding 60W, select the 1606-XL120D (120W) or use a dedicated redundancy module like the 1606-XL120DR.

Q: How much clearance space is required around the power supply for proper cooling?
A: Maintain 25mm (1 inch) above and below the unit for convection airflow. Allow 10mm on the right side for terminal block access. No clearance needed on the left side, enabling tight side-by-side mounting.

Q: Does the unit support DC input voltage for battery backup systems?
A: Yes, the 1606-XL60D accepts 110-300VDC input with minimal leakage current (5.3mA @ 110VDC). However, AC input is preferred for optimal efficiency and hold-up time performance.

Q: What is the typical output rise time during power-up sequencing?
A: Output voltage rises in 5-20ms depending on load capacitance, with a 0.1-second startup delay. This meets power sequencing requirements for most PLC and I/O module combinations.

Q: Is the 1606-XL60D suitable for outdoor installations in extreme climates?
A: The unit operates from -10°C to +70°C, but requires a NEMA 4X or IP65-rated enclosure for outdoor use. In desert climates exceeding 50°C ambient, derate output to 80% or add forced-air cooling.
