Eaton EMR-5000-2B1DB1 Motor Relay - Profibus-DP
Part Number: EMR-5000-2B1DB1
Quick Summary
EMR-5000-2B1DB1 is an Eaton motor relay that provides advanced protection and control for industrial motors across manufacturing lines. It addresses the common challenge of integrating protection, diagnostics, and field communication within compact control panels. This device leverages Profibus-DP over fiber optic, a flexible I/O set, and removable terminals to simplify maintenance and upgrades. While some relays force compromises between protection density and wiring complexity, the EMR-5000-2B1DB1 blends both, backed by backward compatibility with the EMR-4000 base relay. It supports 50/60 Hz systems with a broad voltage window, helping reduce downtime and streamline regulatory compliance in automation projects. For engineers seeking scalable protection with networked communication, this solution delivers tangible business value.
