ABB SDCS-COM81 (3ADT314900R1002) is a dedicated fiber optic communication board developed for ABB SDCS-series DC drive systems. As a core networking component, it acts as a bridge between SDCS drives and upper-level control systems (PLC, DCS, SCADA), supporting bidirectional real-time data exchange and remote drive management.

Equipped with ST-type fiber optic interfaces, the module delivers high-speed, noise-immune communication at up to 100 Mbps, with 2kVrms galvanic isolation between the communication side and drive circuits to protect against voltage spikes and EMI. It supports major industrial protocols including Profinet RT, Modbus TCP, and Ethernet/IP, offering flexible integration with diverse automation platforms.

Designed for industrial-grade reliability, the SDCS-COM81 features a compact plug-in form factor, hot-swap capability for maintenance without system shutdown, and LED indicators for power, status, and communication diagnostics. It operates reliably in temperatures from 0°C to +55°C and complies with CE, UL, and cUL standards, making it ideal for mission-critical drive applications.
