Quick Summary

The Eaton motor relay EMR-3MP0-2A9EB1-1 controls motors in industrial drives and automation panels. Engineers often struggle with integrating relays that support multiple I/O options and fieldbus interfaces in tight control cabinets. Compliances are listed as 'Contact Manufacturer,' so verify CE/UL/RoHS status with Eaton for your region. With 50/60 Hz operation, 5A phase current, and built‑in PROFIBUS‑DP and IRIG‑B options, it streamlines networked motor control. This combination reduces wiring, improves reliability, and shortens commissioning time, delivering tangible efficiency gains for panel builders and OEMs.

FAQs

EMR-3MP0-2A9EB1-1 uses projection mounting with a fixed terminal block configuration. For installation, align the unit with the control cabinet rack, secure the projection mounts, and connect the MP Term Conv and CT term as specified. Use standard DIN rail spacing and route I/O cables to minimize interference and maintain 5A current ratings per channel.
The relay supports 50/60 Hz operation with a 5A phase current, four digital inputs, four digital outputs, and one analog output. These specs are suitable for control and protection tasks in small to mid-size motors such as conveyors, pumps, and fans. The PROFIBUS-DP over D-Sub and IRIG-B interfaces enable networked control and precise timing in automated systems.
Yes. The device includes PROFIBUS-DP over D-Sub RS-485 and URTD Interface IRIG-B, enabling integration with existing PROFIBUS networks and time synchronization across multi-axis drives. When planning your network topology, ensure cable routing minimizes EMI and confirm network addressing matches your PLC or DCS configuration.
Compliances are listed as Contact Manufacturer for EMR-3MP0-2A9EB1-1. To ensure regulatory alignment in your region, contact Eaton or your authorized distributor to confirm CE, UL, RoHS, or any other applicable certifications and documentation before procurement or installation.
