Eaton EMR-3000-2B1BB1 Motor Relay - URTD Interface
Part Number: EMR-3000-2B1BB1
Quick Summary
The Eaton motor relay EMR-3000-2B1BB1 enables reliable motor control for automated drives in industrial facilities. Engineers often battle wiring complexity, integration gaps with fieldbuses, and downtime due to misconfigured I/O; this module addresses those concerns with flexible interfaces and rugged construction. Compliance details should be verified with Eaton—CE, SIL, and IP ratings are commonly required in motor-relay applications, and exact approvals for this model should be confirmed. With 5 A/1 A current protection and metering, 4 digital inputs and 4 outputs, RS-485 communications, and a broad 19–300 VDC / 40–250 VAC power range, the EMR-3000-2B1BB1 delivers reliable, scalable control for panels and automated systems. Its projection mounting and conformal coating further reduce install time and environmental risk.

FAQs
Installation starts with mounting the unit in a suitable panel using the projection mounting method, followed by wiring the four digital inputs and four digital outputs to the control logic. Connect power within the 19–300 VDC or 40–250 VAC range and configure the RS-485 port for Modbus or DNP3 RTU. Ensure proper grounding and interface with the URTD, IRIG-B, and current protection channels for safe, reliable operation.
Key specifications include 5 A / 1 A current protection and metering, 50/60 Hz operation, a broad voltage range (19–300 VDC / 40–250 VAC), and 4× digital I/O with RS-485 communications. This enables proactive motor protection, real-time current monitoring, and integration with existing control networks, reducing fault clearance times and improving overall drive reliability.
Yes. The device is designed for industrial automation with a conformal coating for moisture and dust resistance, broad power compatibility, and robust digital I/O for interlocks and signaling. Its RS-485 fieldbus support and URTD/IRIG-B interfaces make it adaptable to process control and manufacturing environments where reliable motor control and timing synchronization are critical.
Compliance details for EMR-3000-2B1BB1 should be confirmed with Eaton; the datasheet notes 'Compliances: Contact Manufacturer.' In practice, motor-relay products commonly require CE, IP ratings, or SIL verifications depending on the application and region. For exact approvals, request the official certification documentation from Eaton before deploying in a regulated environment.
ROI benefits come from reduced wiring, fewer external relays, and improved reliability through integrated protection and metering. The RS-485 connectivity enables remote diagnostics, lowering field service visits. Maintenance considerations include periodic verification of I/O integrity, checking conformal coating condition in harsh environments, and ensuring firmware/configuration alignment with control networks.
