FAQs
When installing the EMR-4000-2A1EA1, plan for the URTD interface and RS-485/PROFIBUS connectivity, ensure space for eight digital inputs and five digital outputs, and allocate wiring for the 19–300 VDC and 40–250 VAC supply range. Mounting should respect clearance for heat dissipation and allow access to the 8 IO terminals for maintenance. Verify panel grounding and sensitive ground input compatibility to prevent noise-induced faults.
The device supports 5A/1A phase current, eight digital inputs, five digital outputs, and four analog outputs. It offers PROFIBUS‑DP over D‑Sub/RS‑485, URTD Interface, and sensing inputs for Power, Current, and Voltage Protection and Metering. Operating voltage ranges span 19–300 VDC and 40–250 VAC, enabling robust protection and metering across diverse motor loads.
Yes. The EMR-4000-2A1EA1 provides comprehensive motor protection and metering features, including current and voltage protection, zone selective interlocking, and multiple IO signals for interlocking with upstream controls. This makes it well-suited for conveyors, pumps, fans, and other continuous-process equipment where uptime and diagnostic visibility are critical.
Certification details for this model are listed as 'Compliances: Contact Manufacturer'. To verify CE, IP ratings, or SIL status for your region and project, contact Eaton directly or check the latest datasheet and regulatory documents. Always confirm the current certification scope before commissioning in regulated environments.
The motor relay consolidates protection, metering, and versatile IO into a single device, reducing panel wiring and wiring error risk while improving fault visibility. Benefits include lower downtime, reduced maintenance visits, and energy-monitoring data that supports efficiency initiatives. The one-year (or eighteen months from shipment) warranty adds long-term protection, contributing to a lower total cost of ownership on multi‑year automation projects.
