RDCO-03 ABB Bailey

RDCO-03 ABB Bailey Analog Output Modules

Product  Description：

• • • • • • The RDCO-03 is a plug-in expansion module that mounts directly onto the drive's control board. It features fiber optic connectors that utilize the DDCS protocol, which is ABB’s proprietary communication standard for power electronics. This specific version, the RDCO-03, is equipped with 10 MBd (megabaud) optical components. These components are designed for high-speed synchronization and data exchange, making the module suitable for complex multi-drive systems where timing and reliability are critical.

            Product Parameters

            • Module Type: DDCS Communication Option Module

            • Protocol: DDCS (Distributed Drives Communication System)

            • Optical Component Speed: 10 MBd (High speed)

            • Number of Fiber Optic Pairs: Two pairs (Channels CH0 and CH3)

            • Connector Type: Plastic Fiber (POF) or Hard Clad Silica (HCS)

            • Maximum Cable Length: Typically up to 30 meters for Plastic Fiber and up to 200 meters for HCS fiber, depending on the drive's configuration.

            • Compatibility: Compatible with ABB ACS800, ACSM1, and certain DCS800 industrial drives.

            • Power Supply: Powered directly from the drive's control board; no external power source required.

            Product Advantages

            • Electromagnetic Immunity: Because the module uses fiber optic cables instead of copper wiring, it is completely immune to electromagnetic interference (EMI) and radio frequency interference (RFI), which are common in heavy industrial environments.

            • High-Speed Data Transfer: The 10 MBd optical components allow for rapid parameter updates and synchronized control, essential for master-follower applications.

            • Galvanic Isolation: Fiber optics provide total electrical isolation between the drive and the controller, protecting sensitive control equipment from high-voltage surges or ground loops.

            • Compact Integration: The "snap-on" design allows for easy installation within the drive's existing footprint without requiring extra cabinet space.

            Important Considerations and Precautions

            • Fiber Optic Handling: Fiber optic cables are fragile. Do not bend them beyond their minimum bend radius (typically 25 mm to 35 mm) as this can cause signal loss or physical breakage.

            • Connector Cleanliness: The optical tips must be kept free of dust, oil, and moisture. Always use the protective caps when the cables are not plugged in.

            • Pairing Channels: Ensure that the transmitter (TX) on the RDCO-03 is connected to the receiver (RX) on the destination device, and vice versa. Crossing these leads will result in a communication fault.

            • Firmware Compatibility: Ensure the drive’s firmware version supports the RDCO-03 module. Some older firmware versions may require an update to recognize the DDCS communication options.

            • Static Discharge: When installing the module, follow standard ESD (Electrostatic Discharge) procedures to avoid damaging the sensitive onboard electronics.

            Product Applications

            The RDCO-03 is widely used in heavy-duty industrial sectors where precision and reliability are paramount.

            • Master-Follower Drive Systems: Used in applications like paper machines, winders, and cranes where multiple drives must work in perfect synchronization to maintain tension or shared load.

            • Remote I/O and PLC Integration: Connecting a drive to an AC 800M controller or other ABB Advant controllers via a dedicated fiber optic link for real-time monitoring and control.

            • Fieldbus Gateways: Acting as the communication interface when a drive is connected to a fieldbus adapter (like an R-series module) that requires a DDCS link to the drive's main control board.

            • Metals and Mining: Employed in harsh environments where high-power electrical noise makes traditional copper-based serial communication unreliable.
