Eaton EMR-3000-2A1GA0 Motor Relay - IRIG-B Interface
Part Number: EMR-3000-2A1GA0
Quick Summary
The Eaton EMR-3000-2A1GA0 motor relay enables reliable motor control and protection for industrial drives in automation and manufacturing environments. Engineers often face downtime when relays don’t integrate cleanly with modern control architectures, leading to wiring errors and slower commissioning. While explicit SIL, CE, or IP ratings aren’t listed here, Eaton provides standard compliance documentation and best-practice guidelines to assist certification. Designed with flexible I/O and multiple communication options, it reduces wiring complexity, accelerates installation, and improves system uptime. In practice, the unit’s 5A/1A phase current, RS-485 D-Sub interface, and URTD/IRIG-B options support scalable, cost-efficient motor control across diverse plant applications. This makes it suitable for retrofit projects or new builds where reliability and traceability matter, with Eaton's one-year warranty providing added risk protection.
