Main Features and Advantages
Ultra-Slim Footprint for Space-Constrained Panels
The Allen-Bradley 1606-XLE80E measures just 32 mm in width, a design choice that directly addresses the reality of modern control cabinets where DIN rail real estate is at a premium. Panel builders integrating CompactLogix controllers, I/O modules, relays, and safety devices often find themselves short on horizontal mounting space. The slim profile of this power supply allows it to fit alongside other 1606-family components or third-party devices without forcing a larger enclosure or an additional DIN rail row. At 430 grams, the unit is also light enough that rail mounting remains secure without additional support brackets .
Wide-Range Input Simplifies Global Deployment
The Allen-Bradley 1606-XLE80E accepts 100–240 V AC input without a selector switch or jumper configuration. For machine builders exporting equipment to multiple regions, this eliminates the need to stock region-specific power supply variants or risk incorrect voltage settings during commissioning. The same unit operates from North American 120 V mains and European or Asian 230 V supplies with equal stability. DC input capability (110–375 VDC) further extends application flexibility to battery-backed systems or DC distribution architectures .
Dynamic Power Boost for Inductive Loads
Below 45°C ambient, the Allen-Bradley 1606-XLE80E can deliver 120% of rated power temporarily, providing 96 W for short durations. This headroom is valuable when downstream devices draw inrush currents at power-up—contactors, solenoids, and small motor starters often demand two to three times their steady-state current for brief intervals. Without boost capability, the power supply may enter current limit or shut down, causing intermittent startup failures. The boost feature allows the Allen-Bradley 1606-XLE80E to ride through these transient demands without nuisance tripping .
NEC Class 2 Certification for Limited-Energy Circuits
The Allen-Bradley 1606-XLE80E holds NEC Class 2 certification, meaning its output meets the National Electrical Code requirements for limited-energy circuits. This classification can simplify wiring and protection requirements in certain installations, particularly where the power supply feeds devices that are themselves Class 2 rated. For panel builders and integrators, this certification reduces the burden of additional overcurrent protection or enclosure requirements that apply to higher-energy circuits .
Application Field
The is most commonly deployed as the primary 24 VDC power source for industrial control panels housing PLCs, I/O modules, sensors, and communication devices. In a typical CompactLogix or MicroLogix installation, the provides the field-side power for digital inputs, relay outputs, and analog transmitters, while its slim profile allows the entire control system to fit within a compact enclosure. The DC-OK signal output can be wired to a PLC input for power supply health monitoring, alerting operators if output voltage drops below threshold .
Beyond general control panels, the serves in building automation systems where it powers damper actuators, valve controllers, and room sensors. Its wide operating temperature range and IP20 protection suit it to mechanical rooms and ceiling plenum installations where conditions are less controlled than in dedicated electrical rooms. In material handling applications, the power supply feeds photo-eyes, barcode scanners, and small conveyor motor starters—loads that benefit from the 120% boost during simultaneous startup. The is also a common choice for retrofit projects where an existing panel requires a reliable 24 V supply without expanding the enclosure footprint.
