Product Overview

Allen-Bradley 1606-XLE240EE Replacement/Upgrade Solution: Seamless Transition from Legacy Power Infrastructure

The Allen-Bradley 1606-XLE240EE is a 240W, 24VDC output DIN Rail Power Supply from Rockwell Automation’s 1606-XLE series — a workhorse component found in thousands of industrial control panels across manufacturing, oil & gas, water treatment, and discrete automation applications. As legacy installations age and original units approach end-of-service life, sourcing a verified, drop-in replacement becomes a critical procurement priority. TOPNLMS supplies the 1606-XLE240EE as a direct replacement and upgrade solution, fully tested, with a 12-month warranty, and ready for fast international shipment from Xiamen, China.

Whether your facility is running a ControlLogix L7x or CompactLogix L3x controller platform, or managing a legacy SLC 500 or MicroLogix 1400 panel that still relies on the 1606-XLE series for 24VDC bus power, the 1606-XLE240EE slots directly into your existing DIN rail layout without requiring panel redesign. The unit’s 240W continuous output rating, wide input range (85–264VAC), and active power factor correction make it compatible with both legacy single-phase distribution boards and modern energy-efficient switchgear. For panels where the 1606-XLP95E or 1606-XLE120E previously handled lower-load zones, the 1606-XLE240EE provides headroom for I/O expansion or additional 24VDC field devices without rewiring the power distribution rail.

In retrofit projects where engineers are migrating from older FLEX I/O 1794 series racks or Point I/O 1734 modules to newer Compact 5000 I/O 5069 architectures, the 24VDC supply rail is often the first component to be evaluated. The 1606-XLE240EE’s output stability (±1% regulation) ensures that analog input modules — such as the 1756-IF16 or 1734-IE4C — receive clean, noise-free power, which is essential for accurate 4–20mA signal processing in process control loops. Pairing this power supply with a 1606-XLE80E for auxiliary 24VDC circuits or a 1606-XLSBATTERY for UPS backup is a common system architecture in high-availability panels.

For facilities upgrading communication infrastructure alongside power systems — for example, migrating from DeviceNet 1788-DNBO scanner modules to EtherNet/IP using 1783-US8T unmanaged switches — the 1606-XLE240EE provides the stable 24VDC backbone required to power both the network infrastructure and the field I/O simultaneously. Its DIN rail form factor (TS35/7.5 and TS35/15 compatible) means it installs in the same footprint as the unit it replaces, preserving control cabinet space and minimizing installation labor.

Wiring compatibility is a key concern in any power supply replacement. The 1606-XLE240EE uses standard screw-terminal connections for both AC input and DC output, matching the terminal layout of earlier 1606-XLE series units. Field wiring — including PE ground, L1/L2 AC input, and +24V/0V DC output conductors — can be reconnected directly without re-termination or ferrule changes in most installations. The unit’s output terminals accept wire gauges from 0.5mm² to 6mm², covering the full range of typical panel wiring practices.

For PLC programmers and system integrators, the replacement of a power supply unit requires no program changes. The 1606-XLE240EE is a passive infrastructure component; it does not appear in the I/O tree of Studio 5000 Logix Designer or RSLogix 5000, and its installation has no impact on ladder logic, function block diagrams, or structured text routines. Downtime is limited to the physical swap and a brief power-on verification sequence, typically completed within 30–60 minutes by a qualified electrician.

TOPNLMS maintains stock of the 1606-XLE240EE alongside related 1606-XLE series variants and associated system components, enabling consolidated procurement for multi-unit panel builds or emergency replacement orders. All units are inspected and function-tested prior to shipment.

Seamless Upgrade Solutions

A power supply replacement rarely occurs in isolation. In most 1606-XLE240EE upgrade projects, engineers simultaneously address adjacent components to maximize panel reliability and minimize future service calls. For panels running ControlLogix 1756 chassis, the 1756-PA75 or 1756-PB75 chassis power supply handles backplane power, while the 1606-XLE240EE supplies 24VDC to field I/O and sensors — both should be evaluated together during a planned maintenance window. Where redundant power is required, a 1606-XLRED20 redundancy module can be paired with two 1606-XLE240EE units to provide automatic failover without panel redesign.

Terminal block infrastructure is another common upgrade target. Phoenix Contact or Weidmüller DIN rail terminal blocks rated for 24VDC distribution, along with 1492-CABLE series pre-wired interface cables for 1756 or 1769 I/O modules, are frequently ordered alongside the power supply to complete a panel refresh. For facilities adding EtherNet/IP devices during the same outage window, a 1783-US8T or 1783-NATR NAT router may be included in the same procurement package to avoid a second shutdown.

In applications where the 1606-XLE240EE powers analog field instruments, signal isolators — such as the MTL5541 or P+F KFD2-STC4-Ex1 — are often installed in the same retrofit to eliminate ground loop interference introduced by aging cable infrastructure. HMI panels running PanelView Plus 7 (2711P series) or PanelView 800 (2711R series) also draw 24VDC from the same supply rail and should be load-calculated as part of the power budget review before finalizing the replacement unit selection.

Retrofit Guidance FAQ

Q: Can I replace my existing 1606-XLE240E with the 1606-XLE240EE without rewiring?
A: In the vast majority of installations, yes. The terminal layout and DIN rail footprint are compatible. Verify your existing wire gauge is within 0.5–6mm² and that AC input and DC output conductors are correctly identified before reconnection.

Q: Does replacing the power supply require any changes to my PLC program?
A: No. The 1606-XLE240EE is a passive infrastructure component and does not appear in the Studio 5000 or RSLogix I/O configuration. No program modifications, downloads, or controller restarts are required as a result of the power supply swap.

Q: Is the 1606-XLE240EE compatible with both ControlLogix and CompactLogix systems?
A: Yes. It supplies 24VDC to field devices, I/O modules, and communication hardware regardless of the controller platform. It is equally applicable to SLC 500, MicroLogix, ControlLogix, CompactLogix, and Micro800 panel architectures.

Q: What communication protocols does this unit support?
A: The 1606-XLE240EE is a passive DC power supply with no communication interface. It does not participate in EtherNet/IP, DeviceNet, ControlNet, or any other industrial protocol. Protocol compatibility is determined by the I/O modules and controllers it powers.

Q: How much physical space does the unit require in the control cabinet?
A: The 1606-XLE240EE has a standard 1606-XLE series form factor. It mounts on TS35 DIN rail and requires approximately 60mm of rail width. Verify cabinet depth (minimum 150mm recommended) and ensure adequate clearance for convection cooling above and below the unit.

Q: What is the lead time and shipping arrangement?
A: TOPNLMS ships from Xiamen, China. In-stock units are dispatched within 1–3 business days. International express delivery (DHL/FedEx) typically reaches most destinations within 5–10 business days. Emergency orders can be prioritized — contact [email protected] for urgent requirements.
