Eaton Specification Sheet - EMR-3000-2B1EB0
Conformal coated circuit boards and a standard mounting method deliver rugged reliability in dirty or humid industrial settings. This reduces field failures and simplifies installations, translating to lower maintenance costs in manufacturing lines and service-intensive applications. The wide voltage range of 19-300 VDC and 40-250 VAC at 50/60 Hz allows retrofits across legacy equipment without additional power supplies, improving project timelines and reducing spare-part inventories in electrical rooms. Four digital inputs and four digital outputs provide local control and status signaling while enabling metering and protection of motor loads, which translates to predictable performance and reduced risk of unplanned downtime in conveyor systems and pumps. Seamless fieldbus integration is supported through PROFIBUS-DP over D-Sub/RS-485, IRIG-B input, and URTD Interface, simplifying commissioning and enabling precise time synchronization in complex automation environments. The rugged construction, conformal coating, and standard mount also support easier maintenance planning and longer service intervals in demanding industrial environments.

FAQs
EMR-3000-2B1EB0 supports PROFIBUS-DP over D-Sub/RS-485, enabling direct communication with common industrial controllers. Connect the D-Sub/RS-485 lines according to your controller’s RS-485 addressing scheme, set the correct baud rate, and use the four digital inputs and outputs for status and control signals. The standard mounting and rugged, conformal-coated PCB simplify retrofits on existing panels, while the 50/60 Hz operation ensures synchronization with your drive electronics. This reduces wiring complexity and lightweight integration challenges in retrofit projects.
Key specs include 5A current protection and 1A sensing as part of the motor protection and metering features, a wide voltage range of 19-300 VDC and 40-250 VAC, and operation at 50/60 Hz. With four digital inputs and four digital outputs, you can monitor motor status and implement interlocks locally, reducing dependency on external relays. These features collectively improve protection, enable precise control, and support accurate metering for energy management in motor drives.
Yes, the EMR-3000-2B1EB0 includes URTD Interface and IRIG-B input capabilities, which are valuable for time synchronization and coordinated control in security-sensitive environments like power plants. This makes it well-suited for synchronous motor control tasks, time-stamped signaling, and multi-device coordination. Ensure your control system can provide the URTD and IRIG-B signals and configure the device accordingly for reliable timing across the automation network.
Compliances are listed as manufacturer-confirmed for EMR-3000-2B1EB0; verify by consulting Eaton’s datasheet and your regulatory team. In practice, motor relays in this class commonly reference CE and UL marks and IP-rated enclosures; confirm exact certifications with Eaton and ensure the device meets your plant’s safety and environmental requirements before deployment.
The EMR-3000-2B1EB0 consolidates motor protection, metering, I/O, and fieldbus communication in a single unit, reducing panel footprint and cabling. This lowers installation time, minimizes spare parts, and improves uptime through integrated protection and diagnostics. Over time, the device supports tighter control, easier maintenance, and faster fault isolation, delivering measurable gains in productivity and return on investment for automation projects.
