Woodward LR20025 MFR13 Multifunction Protection Relay Module

The LR20025 (Model: MFR13) is a high-precision multifunction protection relay designed for advanced monitoring and control of electrical power systems, particularly in wind turbine and decentralized power generation environments. As part of the Woodward MFR series, the LR20025 (MFR1375M / PMRSU03UV) integrates multiple monitoring functions—including voltage, frequency, and power—into a single compact unit. This module is engineered to provide Class 1 accuracy in current and voltage sensing, ensuring that grid-tie parameters remain within strict operational limits.

Equipped with a specialized CAN bus communication interface, the LR20025 (Multifunction Relay: LR20025) supports complex data exchange with wind turbine controllers and plant SCADA systems. The unit features one discrete input and eight discrete outputs, allowing for flexible logic programming and fault signaling. Its rugged construction and wide sensing range (up to 690 VAC) make it an essential component for protecting generators and switchgear against over/under voltage and frequency fluctuations.
