4-slot chassis for the SLC 500 modular hardware style.

Key specifications

What it is and where it's used

The 1746-A4 is an Allen-Bradley accessory from the SLC 500 range. Typical applications: Small SLC 500 racks. The manufacturer no longer sells this part new (discontinued 2024), which is why it is sourced from surplus stock elsewhere in Europe.

What to check before ordering

• Confirm slot count matches the module set
• 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.
