Overview
The ABB RDCO-03 is a fiber optic communication option module designed for seamless integration with ABB ACS800 series drives and RMIO Motor Control boards. This DDCS (Distributed Drive Control System) communication adapter enables reliable high-speed data exchange across industrial automation systems, supporting multiple communication channels for coordinated motion control and fieldbus integration.
Key Features
- Four fiber optic DDCS channels: CH0, CH1, CH2, and CH3 for flexible system architecture
- Variable communication speed: Operates at 1, 2, or 4 Mbit/s
- Reliable optical transmission: Agilent Technologies Versatile Link fiber optic components
- Low power consumption: 200 mA maximum current
- Compact form factor: Mounts directly to RMIO board or BCU control units
- Industrial-grade protection: IP20 degree of protection
