Eaton EMR-4000-2A1CA1 Motor Relay - URTD Interface
Part Number: EMR-4000-2A1CA1
Quick Summary
The Eaton motor relay EMR-4000-2A1CA1 enables robust motor control in automation panels. Engineers often wrestle with protecting equipment while keeping control networks simple and reliable in harsh industrial environments. Certification details vary by region; consult the manufacturer for CE, UL, or IP ratings applicable to your site. Powered by protective and metering sensing across Voltage, Current, and Power, it supports 19–300 VDC and 40–250 VAC, with URTD and IRIG-B interfaces. In practice, this translates to faster commissioning, enhanced protection, and lower energy costs for industrial automation projects. With Modbus and DNP3 RTU over Ethernet, 8 digital inputs, 4 analog outputs, 5 digital outputs, 5 A and 1 A phase currents, the EMR-4000-2A1CA1 integrates seamlessly with existing plant controls.

Eaton Specification Sheet - EMR-4000-2A1CA1
URTD Interface and IRIG-B time synchronization enable precise coordination across distributed protection schemes, reducing mis-timed events and false trips in large motor drives and networked installations. This capability directly improves system reliability and simplifies fault diagnosis in automation panels. Protection and metering across Voltage, Current, and Power enhances energy management and accelerates fault localization, delivering measurable reductions in downtime and energy waste. Flexible communication and I/O—Modbus / DNP3 RTU over Ethernet RJ-45, 8 digital inputs, 5 digital outputs, 4 analog outputs—facilitate direct PLC/SCADA integration, reducing wiring complexity and speeding commissioning. The option for URTD Interface and Sensitive Ground Input supports safety-critical installations with robust grounding references and precise signal conditioning. The 19–300 VDC / 40–250 VAC range accommodates multi-source power feeds, simplifying standardization across a facility. A compact footprint (8.06 in L × 8.7 in H × 9.72 in W) and a 9.259 lb weight ease panel layout, while Eaton’s warranty (25-000 policy) adds value during system deployment. Zone selective interlocking (1) further enhances fault isolation and workforce safety in dynamic motor networks.
