Actuator Loop Feedback Response and Dynamic Protection Trip Execution

The Woodward IRI1-I5E05D utilizes adjustable fault threshold parameters to process current imbalances and deliver targeted actuator loop feedback response. Upon sensing ground leakage currents exceeding preset values, the unit energizes its SPDT output relay contacts to interrupt downstream circuit breakers or alarm loops. Front-panel visual LED indicators provide immediate local diagnostic feedback, ensuring fail-safe isolation and high noise immunity within 50/60 Hz AC distribution topologies.

Frequently Asked Questions

Q: What power source is required to operate the Woodward IRI1-I5E05D Earth Fault Relay?

A: The relay operates on an auxiliary input supply voltage rating of 230 VAC/DC across a frequency range of 50/60 Hz.

Q: What type of output switching contact configuration is provided on this model?

A: The module is equipped with SPDT (Single Pole Double Throw) output relay contacts for fault signaling and breaker trip control logic.

Q: How is the relay physically mounted within a control cabinet?

A: The unit features a compact enclosure structure designed for standard industrial DIN rail mounting.

Field Installation Guidelines

  • Snap the relay unit securely onto a standard industrial 35 mm DIN rail inside a protective panel structure.
  • Route auxiliary 230 VAC/DC supply connections through dedicated fuse blocks, observing proper terminal polarity and wire gauges.
  • Ensure output relay SPDT wiring is routed separately from low-voltage signaling lines to reduce inductive coupling.
  • Ground all field current transformer (CT) secondary circuits at a single earth ground terminal to prevent loop errors during earth fault sensing.
