Allen-Bradley 1606-XLB240E Basic 24V DC 240 W Power Supply
Description
A 10 A, 240 W Basic-line supply with DC-OK relay and screw terminals
The Allen-Bradley 1606-XLB240E is a Basic-line supply with 24V DC at 10 A (240 W). The XLB family is the most economical group in the 1606 range: it has screw terminals, a single-phase AC input of 100 to 240V and a very high 95.2% typical efficiency, but it has no DC input and no power reserve.
At 49 mm wide it is narrower than the 62 mm Essential and Performance 10 A models, which saves rail space in dense panels. The DC-OK relay contact is included, so a controller can monitor the output.

Basic versus Essential
The Basic line is intended for general machine building where price matters and features such as power boost are not needed. Compared with the 240 W Essential XLE240E, this supply gives up the DC input and the 20 percent reserve, but offers a higher efficiency and a smaller footprint.
The datasheet shows ripple of 100 mV maximum, which is double the 50 mV of the Essential and Performance lines. That is fine for relays, contactors and standard I/O, but sensitive analog or encoder circuits may benefit from a tighter supply.
For cabinet heat planning, the 12.1 W typical loss is low for a 240 W supply, but it still adds to the enclosure load, and the derating of 6 W per degree above 60 C means a hot panel loses capacity quickly. Where the same panel also holds drives, consider a small fan or a larger enclosure rather than relying on the supply to ride through high ambient temperatures.
Practical advice
With a 14 A and 26 A inrush, the upstream breaker must be a B-10 A or C-6 A at minimum. Output current falls from 10 A to 8.6 A when the voltage is adjusted to its highest setting, so do not raise the output for long cable runs without checking the load.
The unit has screw terminals, so tighten them to the torque in the manufacturer’s instructions and recheck after commissioning on vibrating machinery. Operating range reaches -25 to +70 C with derating from 60 C.

About brand
Allen-Bradley is the brand of Rockwell Automation for industrial control: ControlLogix and CompactLogix controllers, I/O systems, PanelView operator terminals, PowerFlex drives, motor control and industrial network equipment. The company began in Milwaukee in 1903, when Lynde Bradley and Dr. Stanton Allen formed the Compression Rheostat Company to make the motor speed controller Bradley had invented in 1901. It took the name Allen-Bradley in 1909 and was bought by Rockwell International in 1985. Since 2001 its owner has been Rockwell Automation, which is still headquartered in Milwaukee, Wisconsin.

| Name | Allen-Bradley Company from 1909 |
| Ownership | Acquired by Rockwell International in 1985 for about USD 1.65 billion; a brand of Rockwell Automation (NYSE: ROK) since 2001 |

Reading Allen-Bradley catalogue numbers
The first digits of an Allen-Bradley catalogue number identify the platform, which tells you what is compatible with what. 1756 is ControlLogix (chassis-based, used for large process and plant control), 1769 is CompactLogix 5370 with Compact I/O, 5069 is CompactLogix 5380 with Compact 5000 I/O, 1734 is POINT I/O, 1794 and 5094 are FLEX and FLEX 5000 distributed I/O, 1746 and 1747 belong to the older SLC 500 family, 1766 is MicroLogix 1400 and 2080 is Micro800. For drives, 25B is PowerFlex 525 and 22B is PowerFlex 40; in a code such as 25B-D010N114, "D" means 380–480 V, "010" is the output current rating, and N114 instead of N104 means the drive has an integrated EMC filter. Many plants in the region still run SLC 500 and older MicroLogix systems, which Rockwell has discontinued, so exact spares and migration to CompactLogix are both common requests.
Where Allen-Bradley products are used
In Oman and the GCC, Allen-Bradley controllers and drives run on oil and gas facilities, water treatment and pumping stations, cement, food and beverage and packaging plants, and on machines supplied by American OEMs. ControlLogix is often the platform for plant control systems, while PowerFlex drives are used on pumps, fans and conveyors.

Ordering Allen-Bradley products: what we need
Send the full catalogue number and the series letter from the label (for example 1756-EN2T Series D), because firmware and compatibility can change between series. For drives, add the motor power, voltage and filter option. For a discontinued SLC 500 or MicroLogix part, tell us whether you need the exact spare or a migration proposal.
