      Information

      Overview Manuals Common Applications Product Precautions
      ABB RDCU-12C is an ACS800 drive control unit containing an RMIO-12C motor-control and I/O board.
      • Three analogue inputs and two programmable 0/4 to 20 mA analogue outputs
      • Six programmable 24 V digital inputs plus a DIIL start-interlock input
      • Three relay outputs
      • ABB PPCS optical-fibre power-section link at 10 MBd

      It processes external analogue and digital control signals, exchanges command data with the inverter or IGBT-supply power section over PPCS, and works with documented I/O, encoder, fieldbus or DDCS options in compatible ACS800 systems.

      Important Notice: ABB directly verifies programmed variant 3AUA0000036521P; confirm the physical label before treating unsuffixed 3AUA0000036521 as the exact variant.

      Important Notice: The first link is the product-parameters PDF prepared only from the cited manufacturer information; the second link is the Apter Power product manual. Confirm the physical nameplate, current manufacturer documents, and host-system requirements before installation or replacement.

      ACS800 motor and inverter control
      Processes control and feedback signals for compatible ACS800 variable-speed drive systems.
      External process I/O
      Interfaces analogue inputs and outputs, digital inputs, a start interlock and relay outputs.
      Encoder-feedback integration
      Accepts a documented RTAC option where the exact ACS800 host and application support it.
      Fieldbus or DDCS integration
      Uses documented option modules for supported fieldbus or DDCS communication paths.
      Follow the exact ACS800 and RDCU installation instructions and verify the programmed hardware identity before commissioning.
      1
      Only qualified electricians may install or service the control unit or drive.
      2
      Disconnect every power source, prevent reconnection, wait five minutes and verify that the power section is discharged before work.
      3
      Use ESD precautions and avoid touching RMIO circuitry or connector contacts.
      4
      Do not force connectors or the enclosure cover during installation.
      5
      Verify that SW TYPE, SW CODE and DEVICE TYPE correspond to the converter hardware and original order before commissioning.

      Technical notes

      Technical notes

      Confirm whether the physical unit carries unsuffixed 3AUA0000036521 or programmed-variant code 3AUA0000036521P; the P suffix must not be omitted for a programmed unit. The loaded SW TYPE, SW CODE and DEVICE TYPE must correspond to the converter hardware and original order before commissioning. The three analogue inputs comprise two differential 0/4 to 20 mA channels and one differential -10/0/2 to +10 V channel. Compatible options are host- and application-dependent; the cited manual documents RAIO, RDIO, RTAC, RPBA/RMBA and RDCO options in permitted positions. No native Ethernet or Modbus function should be claimed without a documented option module. Only qualified electricians may install or service the unit. Disconnect all sources, wait five minutes, verify discharge, use ESD precautions and maintain cooling and electromagnetic separation.

      FAQS

      • What is ABB RDCU-12C?
        It is an ACS800 drive control unit that contains the RMIO-12C motor-control and I/O board.
      • What supply does RDCU-12C require?
        It requires +24 V DC ±10%. ABB gives a typical current of 250 mA without options and a maximum of 1200 mA with options.
      • How many analogue signals can it handle?
        It has three analogue inputs: two programmable differential current inputs and one programmable differential voltage input. It also has two programmable 0/4 to 20 mA analogue outputs.
      • How many digital and relay channels are provided?
        The control unit provides six programmable 24 V digital inputs, one DIIL start-interlock input and three relay outputs.
      • How does RDCU-12C communicate with the power section?
        It uses ABB's 10 MBd PPCS protocol over an optical-fibre link to the inverter or IGBT-supply module.
      • Which option modules can be installed?
        ABB documents RAIO and RDIO I/O modules, RTAC pulse-encoder modules, RPBA or RMBA fieldbus modules where supported, and an RDCO DDCS communication option.
      • Which control panel is supported?
        ABB documents the CDP-312R control panel connection at X39.
      • What is the difference between 3AUA0000036521 and 3AUA0000036521P?
        ABB's direct product page identifies 3AUA0000036521P as RDCU-12C Control Board - Programmed. The unsuffixed base code was not verified on a direct ABB product page in this review, so the actual label must determine whether the item is programmed.
