Eaton EMR-3000-2B1GA1 Motor Relay - Projection
Part Number: EMR-3000-2B1GA1
Quick Summary
Eaton motor relay EMR-3000-2B1GA1 controls and protects motors in automated industrial processes. Engineers often face wiring complexity, limited diagnostics, and slow fault isolation in motor control panels. When selecting relays for critical equipment, verify certifications such as SIL, CE, and IP ratings with the manufacturer. This model combines integrated motor control, protection, and metering with modern communication options to reduce panel footprint, simplify wiring, and improve diagnostics across automation lines. It supports flexible I/O, remote monitoring, and time synchronization to help maintenance teams predict failures and minimize downtime. Its wide voltage range and 50/60 Hz compatibility broaden motor applications and ease integration into existing panels.

Four digital inputs and four digital outputs offer flexible local logic and easy integration with Modbus/RS-485 networks. This reduces wiring complexity and shortens commissioning time, which translates to lower panel costs and faster deployment in manufacturing lines. Current protection and metering provide real-time visibility into motor health, enabling rapid fault detection and load management, which improves uptime and reduces maintenance costs in heavy industry applications. URTD Interface and IRIG-B time input ensure synchronized data across devices and time-stamped events for auditability and compliance in regulated environments. Projection mounting simplifies installation and reduces panel space usage, while the D-Sub RS-485 interface supports robust communication in electrically noisy environments. The combination of zone selective interlocking and a 5A/1A current framework delivers precise motor protection without sacrificing control flexibility. Compliance information should be verified with the manufacturer, and the product’s 4/4 I/O configuration accommodates scalable automation projects. This Eaton relay also supports future upgrades and modular integration within existing control architectures, helping manufacturers optimize capital expenditure and minimize downtime in production lines.

FAQs
EMR-3000-2B1GA1 supports projection mounting and provides four digital inputs and four digital outputs for local control. Plan space for the 8.62 in height, 6.82 in width, and 8.06 in depth, and connect through D-Sub RS-485 for remote monitoring. Ensure proper wiring practices to minimize noise, and use the URTD/IRIG-B interfaces when time synchronization or diagnostics are required.
Key specs include phase current ratings of 5 A and 1 A, voltage operation from 19–300 V DC and 40–250 V AC, and a 50/60 Hz frequency rating. It provides four digital inputs and four digital outputs, a D-Sub RS-485 communication path, and I/O options such as Sensitive Ground Input, IRIG-B, and URTD Interface to support time-stamped data and remote monitoring.
Yes. The device includes current protection and metering features, along with zone selective interlocking to improve fault isolation. Its 5 A / 1 A phase current capability, combined with robust RS-485 communication and four digital I/O lines, makes it well suited for motor protection, monitoring, and control within automated conveyor, pumping, and process lines.
