Key specifications

What it is and where it's used

The 1747-L551 is an Allen-Bradley CPU from the SLC 500 range. Typical applications: Older SLC 500 machine control. The manufacturer no longer sells this part new (discontinued 2021), which is why it is sourced from surplus stock elsewhere in Europe.

What to check before ordering

• Check the OS series and any memory module.
• Processor series and OS series (for example SLC 5/04 OS402), because they affect programming software support
• Chassis slot count and power supply rating against the loaded modules
• Whether the module is fitted with a battery or memory module and what is stored on it

If you are unsure, send us a photo of the label on the existing unit with your request and we will check it against the part number.
