ABB NDCO-03C DDCS Fiber-Optic Communication Board

Product Description

The NDCO-03C is a DDCS fiber-optic communication board engineered for ABB medium-voltage and legacy drive platforms. Installed as an internal option module, it enables deterministic, high-speed data exchange over optical links between drive control units and associated ABB converters or control interfaces.
Designed for harsh electrical environments, the board leverages optical isolation to eliminate electromagnetic interference and ground-loop issues common in copper-based links.

Key Technical Overview

The NDCO-03C functions as a node within ABB’s proprietary Digital Data Communication System. It supports point-to-point and multi-node optical connections used for control, status feedback, and synchronization between drive subsystems. The module is typically supplied as a standalone PCB or as part of ABB spare-part kits such as 64083902, depending on sourcing.

Technical Specifications

Compatibility and System Integration

The NDCO-03C (3BSE017197R1) is commonly used in DDCS-based ABB drive architectures, including ACS-600 family systems. It is intended for internal drive-to-drive or drive-to-control communication and does not act as a fieldbus interface. External protocols such as Profibus or Modbus are handled by separate, dedicated option modules within the same drive platform.

Typical Application Scenarios

This board is deployed in medium- and high-power drive installations where electrical noise immunity and timing accuracy are critical. Typical environments include rolling mills, compressors, pumps, fans, and power-generation auxiliaries. Fiber-optic signaling ensures stable operation over longer distances within large drive cabinets or across coupled converter units.

FAQ

Is the NDCO-03C a fieldbus communication module?
No. The NDCO-03C is dedicated to ABB’s DDCS internal communication. Fieldbus connectivity requires separate option boards.

Can this board replace other NDCO variants?
Replacement compatibility depends on firmware revision, optical channel count, and target drive type. Always verify against the original part number and drive documentation.

Does the weight difference indicate different versions?
Yes. Bare boards are significantly lighter than complete spare-part kits, which may include brackets, fiber leads, or protective packaging.
