      Information

      Overview Manuals Common Applications Product Precautions
      Allen-Bradley 1747-L30C is a fixed-hardware SLC 500 controller with integrated AC/DC input, high-speed counter and relay-output circuits.
      • Combines controller, inputs and relay outputs
      • Provides eighteen sinking DC inputs
      • Includes one high-speed counter input
      • Provides twelve relay output points

      1747-L30C operates within the documented Allen-Bradley SLC 500 fixed hardware controller configuration and approved field interfaces.

      Engineered applications include Compact machine control, High-speed event counting, Mixed-voltage relay commands, Installed SLC renewal.

      Important Notice: Back up the SLC program, identify every input and relay-output group, isolate all supply sources and verify the exact 1747-L30C identity before replacement.

      Important Notice: The first document consolidates verified product and system data. The second provides installation, connection, commissioning and acceptance guidance.

      Compact machine control
      Executes a compact standalone sequence with integral I/O.
      High-speed event counting
      Counts the documented high-speed input independently of normal scans.
      Mixed-voltage relay commands
      Switches approved AC or DC loads through grouped relay outputs.
      Installed SLC renewal
      Restores the exact fixed-controller position while retaining logic and field identities.
      Read the applicable Allen-Bradley instructions before work. Verify 1747-L30C, the installed system and every configured interface before isolation, wiring or commissioning.
      1
      Verify the complete 1747-L30C marking and its assigned Allen-Bradley SLC 500 fixed hardware controller position before work.
      2
      Place the connected compact machine control process in the approved maintenance state.
      3
      Isolate every documented power, signal and stored-energy source before disconnecting conductors or cables.
      4
      Record the installed slot, connectors, conductors, addressing, firmware and software configuration before removal.
      5
      Use ESD-safe handling and protect keyed electrical, fiber or sensor interfaces as applicable.
      6
      Confirm the installed 85 to 265 V AC main supply and 24 V DC field input circuits against the approved project.
      7
      Restore power in a controlled sequence and review device, network and host diagnostics.
      8
      Prove the intended high-speed event counting function and retain the final acceptance result.

      FAQS

      • Which integrated I/O complement identifies Allen-Bradley 1747-L30C?
        1747-L30C provides eighteen 24 V DC sinking inputs, one dedicated high-speed counter input and twelve relay outputs in the fixed-controller assembly.
      • What main supply is documented for Allen-Bradley 1747-L30C?
        The fixed controller accepts an 85 to 265 V AC main supply; field and user-power circuits still require separate wiring verification.
      • How should the sensor supply on Allen-Bradley 1747-L30C be applied?
        The controller provides 24 V DC sensor user power rated 200 mA. Confirm the total connected sensor load before commissioning.
      • Which field-input range applies to Allen-Bradley 1747-L30C?
        The documented sinking inputs use 10 to 30 V DC field wiring and must retain the approved common and polarity arrangement.
      • What loads can the Allen-Bradley 1747-L30C relay outputs switch?
        Rockwell documents 5 to 265 V AC or 5 to 125 V DC operation; each group and load current must match the controlled circuit design.
      • Can Allen-Bradley 1747-L30C output groups use different voltages?
        Yes. The relay groups may use different approved voltages, but every group source must be isolated and identified before service.
      • What must be retained before replacing Allen-Bradley 1747-L30C?
        Retain the program, operating mode, I/O assignments, high-speed counter configuration and all terminal-group identities.
      • How is Allen-Bradley 1747-L30C accepted after installation?
        Restore power in a controlled sequence, verify the program and diagnostics, then test each input, counter function and relay group under safe conditions.
