The ABB RDCO-01C 64606948, also cataloged as the RDCO-01C DDCS Communication Option Module, operates as a dedicated hardware component for high-speed optical data transfer and drive controller interfacing within ABB ACS800 frequency converter platforms.

Hardware Variant & Connector Interface

The RDCO-01C module mounts directly into designated drive expansion slots using internal header pins and retaining fasteners. Primary identification criteria comprise:

• Module Hardware Designation: RDCO-01C

• Factory Code Designation: 64606948

• Interface Type: 20-pin internal board connector

• Communication Architecture: Distributed Drives Communication System (DDCS)

Hardware Specifications

Automation Platform Bus & Deterministic Processing

The RDCO-01C option board utilizes optical DDCS channels (CH0 to CH3) to maintain backplane bus communication velocity Licences and isolate signal processing from ambient electrical noise. Integrated board logic ensures strict firmware flash compatibility across AC 800PEC and ACS800 control units, supporting deterministic networks execution and rapid parameter exchange across Profinet / EtherNet/IP topologies.

Delivery Package Checklist

• 1 x ABB RDCO-01C 64606948 DDCS Module

• 2 x M3 x 8 Fixing Screws

• 1 x Anti-Static Protective Packaging Sleeve

Assembly & Optical Wiring Guidelines

• Power Disconnection

  • Turn off all main power feeds and external 24 VDC auxiliary lines prior to inserting or removing the option card.

• Board Insertion & Mechanical Fastening

  • Seat the module into the slot labeled "DDCS" to engage the 20-pin header, securing it with plastic clips and two M3 x 8 screws to complete the GND earth path.

• Optical Fiber Handling

  • Observe transmitter (V_T) and receiver (V_R) color codes during cross-connection. Do not bend plastic optical fiber cables tighter than a 35 mm minimum radius.

• Cable Maintenance

  • Clean optical fiber cable endpoints with lint-free wipes and isopropyl alcohol before insertion to maintain signal light intensity.

Frequently Asked Questions

• Q: What auxiliary supply voltage and operating current are required for the RDCO-01C module?

  A: The card requires a 24 VDC supply (+/- 10%) and draws an operating current of 200 mA under nominal load conditions.

• Q: What maximum data transfer rate is achieved across the optical DDCS channels?

  A: The module supports optical data communication transmission speeds operating up to 12 Mbps.

• Q: Is hot-swapping supported when installing or removing this communication module?

  A: No, auxiliary drive power must be fully isolated before inserting or unseating the 20-pin backplane connector.

• Q: How is electrical frame grounding established during mechanical mounting?

  A: Frame earthing and GND signal interconnects are established directly via two M3 x 8 mounting screws connected to the drive control board.

• Q: What is the minimum allowable bending radius for plastic fiber optic cables?

  A: Fiber optic lines connected to the optical ports must maintain a bend radius greater than 35 mm to avoid signal attenuation.

• Q: How does firmware flash compatibility affect drive communication setup?

  A: Alignment between control board firmware and module registers guarantees valid telegram structure mapping and predictable timing.

• Q: What are the physical transport package dimensions and total item weight?

  A: The module weighs 0.05 kg with boxed shipping dimensions measuring 9.5 cm in length, 3.6 cm in width, and 3.3 cm in height.

• Q: What optical port color coding rules apply to transmitter and receiver channels?

  A: Transmitters (V_T) are marked with blue or grey color codes, whereas receivers (V_R) feature black connector housings.
