FAQs

EMR-3000-2B0CA1 supports Ethernet-based Modbus/DNP3 RTU over RJ-45 and provides 4 digital inputs with 4 outputs, simplifying panel wiring. Ensure your PLC or SCADA supports Modbus or DNP3 and verify available IO slots in the existing enclosure. The projection mounting simplifies mechanical fitment, while the wide voltage range accommodates both new and legacy drives.
Key specs include a wide supply range of 19–300Vdc and 40–250Vac, 50/60 Hz operation, and current protection/metering for 5A and 1A sensing. The device offers four digital I/O channels and four digital outputs, plus URTD IRIG-B timing for synchronized control. Modbus/DNP3 RTU over Ethernet enables remote monitoring and control across networks.
This relay is well-suited for industrial automation environments needing robust motor protection, remote monitoring, and interlocking. Industries like packaging, material handling, process lines, and power systems benefit from zone selective interlocking, precise timing, and energy metering to improve uptime and energy efficiency.
Compliances are listed as 'Contact Manufacturer' for Eaton EMR-3000-2B0CA1, so confirm exact certifications (such as CE marking, IP enclosure rating, and safety certifications) with Eaton for your target market. For critical timing and synchronization needs, IRIG-B compatibility should be validated against your system specification.
By consolidating motor protection, metering, and network communication in a single unit, you reduce wiring complexity and PLC IO needs, lowering commissioning time and spare parts. Real-time current sensing and energy data support better maintenance planning and can contribute to reduced energy waste and improved overall equipment effectiveness (OEE).
