FAQs
Begin by selecting a panel location with adequate depth for the 8.06 in length. Align the projection mounting holes, secure the unit with compatible hardware, and connect the four digital inputs and four digital outputs alongside the single analog output. Route the fieldbus connections for IRIG-B timing and Profibus-DP over fiber optic ST carefully to minimize EMI. Verify 50/60 Hz supply and confirm cable termination per the installation guide before commissioning.
The EMR-3000-2A0DA1 supports IRIG-B timing and PROFIBUS-DP communication over fiber optic ST, enabling precise synchronization and robust remote diagnostics in distributed motor control schemes. It also exposes four digital I/O channels and one analog output for flexible interface with PLCs and other automation equipment, simplifying system integration in existing plant architectures.
Yes. The relay includes sensing inputs for current protection and metering, plus configurable I/O to monitor motor state. With 5A/1A phase current capability and 50/60 Hz operation, it supports standard motor loads while providing protective features that help reduce fault-related downtime and extend motor life when used with proper protection strategies.
Compliances are listed as contact manufacturer, so confirm CE, SIL, IP ratings directly with Eaton for your region and application. The warranty offers one year from installation or eighteen months from shipment, whichever occurs first, providing a clear window for commissioning, maintenance planning, and supplier support in initial usage.
Prioritize clean fiber optic terminations for the Profibus-DP link, secure proper heat dissipation in the panel, and maintain organized cabling to avoid interference. Utilize the projection mount for quick alignment, ensure power conditioning for 50/60 Hz supply, and leverage the current protection and metering features to detect anomalies early, reducing unplanned downtime on conveyors and automated lines.
