Description

Designed for integration with RMIO motor control and I/O boards, the RDCO-01 module provides multi-channel Distributed Drives Communication System (DDCS) functionality. This communication option card mounts directly to RDCU control units and BCU units, establishing high-speed fiber optic links between drives and external control systems. The board features four distinct communication channels (CH0 to CH3), enabling parallel connections to PLC/fieldbus adapters, decentralized I/O, master/follower drive networks, and engineering PC tools. High-speed data transmission is managed via dedicated optical components, ensuring electrical isolation and noise-immune signaling in demanding industrial environments.

Features

  • Four independent fiber optic transmitter/receiver channel pairs (CH0, CH1, CH2, and CH3).
  • Supports selectable communication speeds of 1, 2, or 4 Mbit/s.
  • Direct physical and electrical interface via a 20-pin pinheader.
  • Compatible with Plastic Optical Fiber (POF) and Hard Clad Silica (HCS) cables on 10 MBd channels for extended distances.
  • Compact footprint designed for direct internal mounting within the drive enclosure.

Applications

  • Coordinated master/follower multi-drive configurations in industrial automation.
  • Integration of ABB ACS800 series drives into overriding PLC and DCS architectures.
  • Decentralized I/O expansion and supply unit communication.
  • Drive commissioning, diagnostic monitoring, and parameterization via PC-based engineering tools.

Installation Guidelines

  • Ensure the host drive and RDCU/BCU unit are completely powered down and safe discharge times have elapsed before commencing installation.
  • Align the 20-pin female connector on the RDCO-01 with the matching male header on the RMIO board, pressing firmly to seat the module.
  • Secure the board using the provided mechanical fasteners to guarantee proper grounding, shielding, and vibration resistance.
  • Observe the minimum bend radius specified by the fiber optic cable manufacturer to prevent signal attenuation or physical damage to the core.

FAQ

What is the primary function of the ABB RDCO-01 module?

The RDCO-01 is a DDCS communication option module that adds four high-speed fiber optic channels to ABB RMIO motor control and I/O boards, enabling communications between drives, PLCs, master/follower configurations, and PC commissioning tools.

Which channels on the RDCO-01 support HCS and POF fiber optic cables?

The 10 MBd channels (CH0, CH2, and CH3) support both Plastic Optical Fiber (POF) and Hard Clad Silica (HCS) cables, allowing for longer communication distances than standard 5 MBd channels.

What drives are compatible with the RDCO-01 module?

It is primarily designed for ABB industrial drives, such as the ACS800 series, utilizing RMIO boards, RDCU control units, and BCU units.

What are the channel assignments for the RDCO-01 module?

CH0 is assigned to the overriding system (fieldbus adapter), CH1 is for I/O options and supply units, CH2 manages the master/follower link, and CH3 is dedicated to PC tools.
