No online seller is an authorized Allen-Bradley distributor, so "factory-sealed original packaging" claims don't guarantee a part is new or current-revision. We sell genuine surplus and refurbished units, sourced through trusted channels, inspected and tested, and shipped from the USA, never overseas. Backed by our own 1-year warranty.
What does surplus mean?
"Surplus - Tested (With Warranty)" refers to surplus industrial automation equipment that has been inspected and tested for functionality by PLC Department technicians and verified to be in working condition.
"Surplus" can include items that are:
- New Surplus: Unused items that may have been stored for an extended period or removed from inventory without ever being installed.
- Used Surplus: Previously installed or used items that have been tested and verified to function properly.
- Refurbished Surplus: Items that have undergone repair, reconditioning, or component replacement to restore functionality.
All surplus items may exhibit minor cosmetic wear. Each item is backed by PLC Department's 1-year functional warranty.

Description
Allen-Bradley 1747-L552 | SLC 500 SLC 5/05 Ethernet Processor
The Allen-Bradley 1747-L552 is an SLC 5/05 series processor from the Rockwell Automation SLC 500 product line, designed for reliable control in industrial automation applications with built-in EtherNet/IP communication. This processor combines robust memory capacity with fast scan performance, making it well suited for mid-range control systems requiring network connectivity.
Equipped with 32K words of total user memory—28K words available for program or data and an additional 4K words dedicated to data—the 1747-L552 provides ample space for complex control logic. It supports a maximum I/O configuration of 4,096 inputs and 4,096 outputs, along with up to 480 local analog I/O points, accommodating a wide range of system architectures.
Performance is optimized with a typical program scan time of 0.9 ms per Kword and an I/O scan time of just 0.225 ms, enabling responsive real-time control. The unit draws a maximum load current of 1 amp at 5V DC and dissipates 4 total watts of heat, supporting efficient panel integration.
