      Overview Manuals Common Applications Product Precautions
      Allen-Bradley 1746-A7 is a seven-slot SLC 500 modular chassis that provides the mechanical mounting and backplane connection for the processor or communication adapter, power supply and installed SLC modules.
      • Seven-slot backplane: Accepts a seven-position SLC modular hardware arrangement.
      • Modular system support: Hosts the documented processor or communication adapter, power supply and SLC modules.
      • Four-tab mounting: Uses four chassis mounting tabs for a controlled panel installation.
      • Backplane distribution: Distributes the documented 5.1 V DC and 24 V DC backplane capacity to installed modules.

      Match the complete 1746-A7 chassis identity, mount it with all four chassis tabs and verify every installed module, power supply and backplane connection before commissioning.

      Important Notice: Confirm the complete Allen-Bradley 1746-A7 identity and controlled configuration before commissioning.
