ABB 3BHE039426R0101, with the part number UFC912A101, is an essential EOI (External Output Interface) module engineered by ABB exclusively for the ACS6000 series medium‑voltage (MV) drive systems. It functions as the primary communication and signal‑processing interface between the drive’s power unit and the main control cabinet, ensuring seamless, safe, and high‑speed data transfer in high‑power industrial applications.

As a core component in the ACS6000 drive architecture, the 3BHE039426R0101 handles the conversion, isolation, and transmission of critical control and status signals. It receives TTL‑level digital trigger signals from the main controller, amplifies and conditions these signals, and transmits them via fiber‑optic links to the power modules (e.g., IGCT/IGBT) for precise switching control. Simultaneously, it collects fault signals, temperature data, and operational status from the power section, converting them into standardized signals for the controller’s monitoring and protection logic.

A key design highlight is its fiber‑optic communication capability, which eliminates electromagnetic interference (EMI) in high‑voltage, high‑current environments, ensuring signal integrity and system stability. The module provides ≥2.5kV AC isolation (1 minute) between the control and power sides, protecting low‑voltage control circuits from high‑voltage spikes and enhancing overall system safety.

Powered by a 24V DC control supply, the 3BHE039426R0101 operates reliably in a wide temperature range of ‑20°C to +60°C, with storage tolerance from ‑40°C to +70°C. Its compact, plug‑in design (80 × 90 × 23 mm, approx. 0.5 kg) enables easy installation and replacement in standard ABB drive chassis, minimizing maintenance downtime.

Fully compatible with ABB ACS6000 MV drives and supporting both new installations and retrofits, the 3BHE039426R0101 (UFC912A101) is a genuine ABB spare part, certified CE, UL, and RoHS, ensuring long‑term reliability in mining, cement, metallurgy, and energy sectors.
