Product Description

ABB UFC911B106 3BHE037864R0106 Fiber Optic Communication Interface Module (AC 800PEC Series)

High-Speed Fiber Communication for AC 800PEC Excitation & Power Electronics Control Systems

1. Product Overview

The ABB UFC911B106 3BHE037864R0106 is a high-performance fiber optic communication interface module specifically engineered for ABB AC 800PEC excitation systems and power electronics control platforms. It serves as a critical bridge between the AC 800PEC controller and remote I/O modules, field devices, or upper-level DCS/SCADA systems, enabling high-speed, interference-free data transmission via fiber optic networks. Equipped with dual redundant fiber ports (multi-mode), this module supports a maximum transmission distance of 2 km, ensuring reliable communication 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 integration with ABB's proprietary communication protocols, it is ideal for mission-critical applications in power generation, metallurgy, petrochemicals, and renewable energy sectors where uninterrupted data exchange is essential for system stability and operational safety.

5. Installation & Maintenance

Installation Steps

• Mounting: Install into AC 800PEC standard rack; secure with locking clips to ensure stable backplane connection.

• Fiber Wiring: Connect multi-mode fiber cables (ST connectors) to redundant ports; ensure minimal bend radius (≥ 30 mm).

• Power Connection: Wire 24 V DC power supply to terminal blocks; verify polarity to avoid damage.

• Configuration: Set communication parameters (protocol, IP address) via ABB Control Builder software.

• Testing: Power on module; check LED link indicators; verify data transmission with controller and remote devices.

Maintenance Tips

• Daily: Inspect LED indicators (Power, Link Active, Fault); monitor system logs for communication errors.

• Weekly: Clean fiber optic connectors with lint-free cloth and isopropyl alcohol; check for cable damage.

• Monthly: Test redundant link switchover by disconnecting the primary fiber port; verify uninterrupted communication.

• Quarterly: Measure optical power levels to ensure signal integrity; check terminal block tightness.

• Annual: Update module firmware; inspect rack ventilation; replace aging fiber cables if necessary.
