Quick Summary

Eaton motor relay EMR-3000-2B0EB1 delivers reliable motor control for industrial automation applications. This compact, feature-rich relay is designed to simplify wiring, protection, and diagnostics across automated lines. In practice, engineers seek solutions that reduce downtime and improve fault isolation when integrating motor control with PLCs, HMIs, and fieldbus networks. Key considerations include robust interfaces such as URTD and IRIG-B, and modular communications over RS-485 for PROFIBUS-DP. While this module is compatible with Eaton’s E-Series ecosystem, verify compliance and certifications with the manufacturer to ensure regional approvals. By combining ample I/O, current protection, and durable construction, it supports improved uptime, safer operation, and streamlined maintenance in industrial automation environments.

FAQs

EMR-3000-2B0EB1 communicates over PROFIBUS-DP using a D-Sub RS-485 interface, so plan the panel wiring to keep shielded RS-485 lines short and free from high-current conductors. Use the 4DI/4DO I/O to interlock motor start/stop signals and wire URTD/IRIG-B for time-critical diagnostics. Confirm the network’s baud rate and addressing per the host PLC, then perform a staged boot to verify bus topology and device acknowledgment.
The unit provides 5A and 1A phase current protection/meters, with 4 digital inputs and 4 digital outputs. It operates at 50/60 Hz and supports IRIG-B URTD interfaces for time synchronization, along with RS-485 PROFIBUS-DP communications. This combination enables precise motor control, fast interlocks, and reliable data exchange within standard industrial power environments.
Yes. With current protection/meters, multiple I/O points, and robust fieldbus support, EMR-3000-2B0EB1 is well-suited for conveyors and packaging lines where reliable motor control, quick fault detection, and tight interlocks are essential. Its conformal coating enhances reliability in challenging factory environments, reducing maintenance frequency and downtime.
Compliance details for EMR-3000-2B0EB1 are controlled by the manufacturer. While common Eaton motor relays often align with major standards, always request current certification documentation from Eaton to confirm CE, UL, IP ratings, and region-specific approvals before deployment in regulated environments.
The product warranty is one year from installation or 18 months from shipment, whichever comes first, providing post-sale support and reducing owner risk. Combined with 4DI/4DO I/O, robust diagnostics, and straightforward integration into an Eaton ecosystem, this translates to lower maintenance costs, faster deployment, and improved uptime for automated production lines.
