Eaton EMR-3000-2B1FA1 Motor Relay - URTD Interface
Part Number: EMR-3000-2B1FA1
Quick Summary
Eaton motor relay is a compact controller that optimizes motor start/stop sequences and protection in industrial automation. Engineers often struggle with wiring complexity, unreliable fault signaling, and inconsistent timing across remote panels. The EMR-3000-2B1FA1 addresses these challenges by integrating current protection and metering with a robust fiber optic Modbus RTU link and IRIG-B time synchronization. With URTD Interface and Sensitive Ground Input, it enhances safety and data integrity in mission-critical applications. The device's 4 digital inputs and 4 digital outputs enable lean panel design, while its projection mounting supports flexible installation in constrained enclosures. For procurement and retrofit projects, this Eaton relay delivers reliable performance, simplified integration, and lower total cost of ownership over the product life cycle.
