FAQs

Begin with ensuring the projection mounting alignment specified for a secure fit. Connect the 4 digital inputs/outputs and wire the 5A/1A current paths to the motor circuit. Use the D-Sub RS-485 for communications with the PLC or SCADA, and verify IRIG-B or URTD interface settings if time synchronization or remote timing is required. Confirm panel clearance and grounding to maintain signal integrity and thermal performance.
It supports 19–300 VDC and 40–250 VAC operation at 50/60 Hz. The device handles 5A and 1A phase currents, includes four digital inputs and four digital outputs, and offers IRIG-B and URTD interfaces for timing and data integration with control systems.
Yes. The model lists Zone Selective Interlocking (ZSI) with a value of 1, enabling faster, selective tripping and coordinated protection in multi-motor configurations, which minimizes electrical disturbances and improves system stability.
The relay includes a D-Sub RS-485 interface for industrial communication, plus IRIG-B and URTD inputs, enabling clock synchronization and advanced monitoring. This makes it compatible with common automation architectures and timing systems in manufacturing environments.
Eaton provides a warranty policy (25-000) with one year from installation or eighteen months from shipment, whichever occurs first. For detailed terms and regional support, contact Eaton or your authorized distributor to verify coverage and service options.
