The ABB UFC911B108 3BHE037864R0108 is a high-performance long-distance fiber optic communication interface module tailored for ABB AC 800PEC power electronics control systems and UNITROL excitation platforms. It acts as a critical communication bridge between the AC 800PEC main controller, remote I/O clusters, field devices, and upper-layer DCS/SCADA systems, enabling interference-free, high-speed data transmission over extended distances via single-mode fiber networks. Equipped with dual redundant fiber ports, this module supports a maximum transmission distance of 20 km—a key upgrade over multi-mode variants—ensuring stable data exchange even in harsh industrial environments with strong electromagnetic interference (EMI), high vibration, and extreme temperature fluctuations (-25°C to +70°C). With 2500 V AC galvanic isolation between electrical and optical interfaces, built-in link fault detection, and seamless compatibility with ABB’s proprietary PEC communication protocol, it is engineered for mission-critical applications in power generation, renewable energy, metallurgy, and petrochemical sectors where long-distance, uninterrupted data communication is essential for system stability and operational safety.
