Eaton motor relay EMR-3000-2B0BB0 - RS-485, Conformal Coat
Part Number: EMR-3000-2B0BB0
Quick Summary
Eaton motor relay is a high-density control device that manages motor switching and protection in industrial drives. Engineers often struggle with integration overhead, diagnostics, and exposure to harsh shop floors when deploying relays in crowded control panels. Common certifications for this class include CE and UL safety markings, plus IP-rated protection in regional variants; check the official Eaton datasheet for exact approvals. In practice, this model reduces downtime in motor control and industrial automation environments through robust RS-485 communication, conformal-coated circuitry, and 4 in/4 out I/O aligned to standard drive architectures, delivering measurable efficiency gains. This aligns with procurement goals for reliable uptime and lower lifecycle costs.

FAQs
The EMR-3000-2B0BB0 is designed for standard mounting in control panels with dimensions of 8.06 in length, 8.62 in height, and 6.82 in width. Its form factor supports installation in typical DIN-rail or panel-mounted configurations alongside existing motor drives, with ample space for RS-485 wiring, URTD/IRIG-B interfaces, and 4 in/4 out I/O wiring.
This model provides four digital inputs and four digital outputs for local control and signaling, plus sensing inputs for current protection and metering. The phase current rating is 5A and 1A, while the unit supports RS-485 Modbus RTU communication, enabling reliable remote data exchange with PLCs and SCADA systems.
Yes. The device supports Modbus RTU over RS-485 and includes URTD Interface and IRIG-B timing options, which facilitates precise synchronization and data integration with PLCs and SCADA platforms, reducing wiring complexity and improving cross-system visibility in automated motor networks.
The motor relay uses conformal coating on its circuit boards to resist moisture, dust, and temperature variation, improving reliability in challenging environments such as wash-down areas and outdoor or dusty production floors. Always verify regional compliance and suitable enclosure protection for your specific application.
