Product details
ABB 3BHE032025R0101 (PC D235 A101 / PCD235A101) – Exciter Control Module
The ABB 3BHE032025R0101, also known as PC D235 A101 or PCD235A101, is a high-precision exciter control module designed to regulate generator field current with exceptional accuracy. Built for demanding industrial environments, it ensures stable voltage output and robust performance in power generation systems.
Compact yet powerful, this module is built to withstand harsh conditions with an operational temperature range from –20 °C to +70 °C and humidity up to 95% non‑condensing. It features multiple communication interfaces—including RS‑232, RS‑485, and Modbus—allowing seamless integration into existing networks.
Designed for precision and efficiency, the PCD235 handles high current loads and offers flexible control in both two‑quadrant and four‑quadrant modes. It excels in applications such as power plants, industrial motors, and heavy machinery where consistent voltage control and regeneration capabilities are essential.
With its rugged IP‑rated design and smart diagnostics, this module promotes easy maintenance and minimal downtime. Engineers benefit from intuitive operation and reliable system integration, backed by ABB’s reputation for quality and longevity.
