Product Short Description
The ABB RDCO-04C is a high-performance, four-channel fiber optic communication module designed for ABB industrial drive systems, primarily the ACS800 series. It implements the DDCS (Distributed Drives Communication System) protocol, enabling reliable, noise-immune data exchange between drive control units, I/O modules, fieldbus adapters, master/follower drives, and PC configuration tools. The “C” suffix denotes a coated circuit board, enhancing resistance to harsh industrial environments, moisture, and contaminants. This module supports 10 MBd optical components across all four channels, offering the highest speed and longest reach within the RDCO family, making it ideal for complex multi-drive systems and applications requiring robust, long-distance communication. It is compatible with both Plastic Optical Fiber (POF) and Hard Clad Silica (HCS) cables, providing flexibility in installation and distance requirements.

Functional Features
High-Speed, Four-Channel Communication
- Quad 10 MBd Optical Links: All four channels operate at 10 MBd, delivering the fastest data transfer rate in the RDCO series, supporting high-bandwidth, real-time control applications.
- Standard Channel Assignments:
- CH0: Connects to overriding systems or fieldbus adapters (e.g., Profibus, Modbus).
- CH1: Links to I/O option modules and external supply units.
- CH2: Establishes master/follower drive synchronization for coordinated motion control.
- CH3: Provides a direct connection to PC tools (DriveWindow Light) for configuration, monitoring, and diagnostics (ACS800 exclusive).
- Flexible Fiber Support: Works with POF for short-distance, cost-effective installations and HCS for longer distances (up to hundreds of meters) with lower signal attenuation.
Industrial-Grade Reliability & Protection
- Coated Circuit Board: The “C” variant features a protective coating, significantly improving resistance to dust, humidity, chemical vapors, and vibration in harsh industrial environments.
- Galvanic Isolation: Complete electrical isolation between the communication bus and the drive’s control electronics eliminates ground loops and protects sensitive circuitry from electrical noise and surges.
- EMC Compliance: Rigorously tested to meet strict industrial EMC standards, ensuring stable operation in electrically noisy environments with motors, drives, and high-power equipment.
Seamless Integration & Scalability
- Plug-and-Play Installation: Designed as a direct add-on for RMIO boards and RDCU/BCU control units, available as factory-installed or retrofit kits.
- Multi-Drive Networking: Enables the creation of complex, distributed drive systems with master/follower configurations, allowing precise synchronization of multiple motors.
- PC Tool Connectivity: Direct fiber link to ABB’s DriveWindow software for real-time parameter adjustment, performance monitoring, fault logging, and firmware updates.
- Fieldbus Compatibility: Serves as a bridge between the DDCS drive network and higher-level fieldbus systems (e.g., Profibus, EtherCAT), integrating drives into factory-wide automation architectures.
Diagnostics & Status Monitoring
- Built-in Link Status: The module continuously monitors the health of all four fiber optic links, detecting faults such as cable breaks or signal loss.
- Drive Integration: Fault information is communicated directly to the host drive, which can trigger alarms, log events, or initiate protective actions.
- Remote Access: Enables remote monitoring and troubleshooting of the entire drive network via the connected PC tool or fieldbus system, reducing on-site maintenance needs.
