Product Description
Woodward IRI1-I5E05D Current Relay
Product Overview
- The Woodward IRI1-I5E05D is a digital current relay designed for overcurrent protection in electrical systems, commonly used in power generation, distribution, and industrial applications such as generator sets, motors, and transformers. Part of Woodward’s IRI1 series, this microprocessor-based relay provides reliable monitoring and protection against overcurrent conditions, ensuring the safety and stability of connected equipment. The IRI1-I5E05D model is configured for specific current and voltage inputs, with the "I5E05D" designation indicating a 5 A nominal current input, extended functionality, and specific firmware or hardware features. It offers precise protection settings, fault diagnostics, and communication capabilities for integration into modern power management systems. Compared to Woodward’s genset controllers (e.g., EasyGen-3500-5, 8440-2087), excitation systems (e.g., DECS-100-B15), or transfer switch controllers (e.g., DTSC-200), the IRI1-I5E05D focuses solely on current-based protection, not engine or generator control. It is distinct from Woodward’s electronic governors (e.g., DYN1-10784-003-0-12), actuators (e.g., 8408-921), and other modules (e.g., 5466-1510 CPU).
