Eaton EMR-5000-2A1CA1 Motor Relay - Modbus TCP
Part Number: EMR-5000-2A1CA1
Quick Summary
EMR-5000-2A1CA1 motor relay is designed to deliver robust motor protection and networked control for industrial drives. Operators often struggle with protection schemes that fail under peak loads, complicate diagnostics, and hinder remote monitoring. Certification specifics should be confirmed with the manufacturer, but this model provides Ethernet-based Modbus TCP or DNP3 TCP/UDP communications for scalable protection. With 16 digital inputs, 9 digital outputs, and removable terminals, it supports reliable sensing and fast field wiring. Designed for projection mounting and 50/60 Hz operation across 19–300 Vdc and 40–250 Vac supplies, it fits a wide range of motor protection schemes. Together with zone selective interlocking and metering options, it helps industrial teams meet uptime targets and optimize maintenance planning.
