Product Details

1606-XLE240E Product Description

The Allen-Bradley 1606-XLE240E is a 240W, 24VDC DIN-rail mounted power supply engineered for seamless integration into Rockwell Automation's 1606-XLE series control architecture. Designed to deliver stable, regulated DC power across multi-tier industrial automation systems, the 1606-XLE240E serves as the foundational power layer for ControlLogix, CompactLogix, and GuardLogix controller platforms. Its robust design ensures consistent voltage output under variable load conditions, making it a preferred choice for demanding process control, discrete manufacturing, and safety-critical applications where power integrity directly impacts system uptime and diagnostic accuracy.

In modern industrial control architectures, the power supply is not a peripheral component — it is the backbone of system reliability. The 1606-XLE240E is built to support layered automation environments where the control layer, I/O layer, communication layer, HMI layer, and field device layer must operate in synchronized harmony. Its wide input voltage range (85–264VAC) accommodates global installation environments, while its active power factor correction and high efficiency rating minimize heat generation and reduce panel cooling requirements. The unit's integrated diagnostics and DC OK signal output allow the host PLC or safety controller to monitor power status in real time, enabling predictive maintenance workflows and reducing unplanned downtime.

The 1606-XLE240E is architected to power and stabilize a complete Rockwell Automation control platform. In a typical ControlLogix 5580 or CompactLogix 5380 deployment, the 1606-XLE240E supplies regulated 24VDC to the controller backplane, distributed I/O chassis, and field-side terminal blocks simultaneously. When paired with the 1756-PA75 or 1756-PB75 ControlLogix chassis power supply, the 1606-XLE240E handles the 24VDC field power rail, ensuring clean separation between logic power and field power — a critical design principle in high-noise industrial environments.

For I/O layer integration, the 1606-XLE240E directly powers 1734 POINT I/O adapter modules and 1769 CompactLogix I/O expansion racks, maintaining signal integrity across analog input modules such as the 1756-IF16 and digital output modules such as the 1756-OB16I. In communication-intensive architectures, the power supply supports 1783-BMS10CGP Stratix managed Ethernet switches and 1756-EN2T EtherNet/IP communication modules, both of which require stable 24VDC for deterministic network performance.

At the HMI layer, the 1606-XLE240E provides reliable power to 2711P PanelView Plus 7 operator terminals installed within the same control panel, eliminating the need for a separate HMI power rail and simplifying panel wiring. For safety-critical applications, the unit integrates with 1791DS GuardLink safety I/O modules and 440C-CR30 safety relay modules, where stable DC power is a prerequisite for SIL 2 / PLd compliance. In redundant power architectures, two 1606-XLE240E units can be paralleled using the 1606-XLERED redundancy module, providing N+1 power redundancy for continuous process applications in oil and gas, water treatment, and pharmaceutical manufacturing.

The 1606-XLE240E also supports field device layers including 889D series cordsets, 871TM proximity sensors, and 440N safety switches, all of which operate on 24VDC and benefit from the supply's low ripple and noise specification (<50mV peak-to-peak). This makes the 1606-XLE240E a universal power backbone across the full automation stack — from the controller backplane to the last field sensor in the loop.

Discrete Manufacturing: In automotive body shop and assembly line automation, the 1606-XLE240E powers ControlLogix-based motion control systems managing servo drives, vision systems, and robotic end-of-arm tooling. Its high efficiency and compact DIN-rail form factor allow dense panel layouts typical of automotive Tier 1 supplier facilities.

Power Generation & Utilities: In substation automation and power distribution control panels, the 1606-XLE240E supplies 24VDC to protection relay panels, RTU communication modules, and SCADA interface cards. Its wide operating temperature range (-25°C to +70°C) and ATEX Zone 2 certification make it suitable for outdoor switchgear enclosures and hazardous area installations.

Oil, Gas & Petrochemical: Upstream and midstream pipeline control systems rely on the 1606-XLE240E to power remote I/O panels connected via EtherNet/IP or DeviceNet to central ControlLogix controllers. The unit's redundancy capability via the 1606-XLERED module is particularly valued in wellhead control panels where power interruption is not acceptable.

Water & Wastewater Treatment: Municipal water treatment SCADA systems use the 1606-XLE240E to power CompactLogix controllers, 1734 POINT I/O modules, and Stratix network switches distributed across pump stations and filtration facilities. The supply's long MTBF and DIN-rail mounting simplify maintenance in unmanned remote stations.

Mining & Metals: In conveyor control, crusher automation, and ore processing systems, the 1606-XLE240E provides stable power to high-vibration environments where lesser power supplies fail prematurely. Its robust mechanical design and wide input range accommodate the variable grid conditions common in remote mining operations.

Packaging & Food Processing: High-speed packaging lines using CompactLogix motion controllers and 1734 POINT I/O benefit from the 1606-XLE240E's fast transient response, which maintains stable 24VDC during rapid load changes caused by servo drive acceleration and deceleration cycles. Its IP20 enclosure rating is compatible with standard control panel installations in food-grade environments.

Q1: Can the 1606-XLE240E be used in a redundant power configuration for a ControlLogix system? Yes. The 1606-XLE240E supports N+1 redundancy when paired with the 1606-XLERED redundancy module. Two units can be connected in parallel with automatic load sharing and failover. In the event of a primary supply failure, the secondary unit assumes full load without interruption, maintaining system uptime in continuous process applications. This configuration is recommended for SIL-rated safety systems and 24/7 production environments.

Q2: Is the 1606-XLE240E compatible with both ControlLogix and CompactLogix architectures? Yes. The 1606-XLE240E provides 24VDC field power compatible with all Rockwell Automation controller platforms that require external 24VDC, including ControlLogix 5580, CompactLogix 5380, GuardLogix 5580, and Micro850 systems. It is also compatible with 1734 POINT I/O, 1769 Compact I/O, and 1756 ControlLogix I/O modules. No firmware or configuration changes are required — the supply is plug-and-play within the 1606-XLE series ecosystem.

Q3: What warranty and pre-shipment testing does the 1606-XLE240E include? Every 1606-XLE240E supplied by NANKMOS includes a 12-Month Warranty covering manufacturing defects and functional failures under normal operating conditions. Prior to shipment, each unit undergoes full-load burn-in testing, output voltage verification, DC OK signal validation, and protection circuit testing (OVP, OCP, short circuit). Units are shipped with anti-static packaging and include a test report upon request. Expedited global shipping is available with typical lead times of 3–7 business days.
