FAQs
Plan for projection mounting and allocate space for four digital inputs and four outputs, plus one analog in and one analog out. Ensure supply within 19-300 Vdc or 40-250 Vac and provide proper isolation for RS-485 and Ethernet RJ-45 connections. Use the provided MP-3000 to EMR-3MP0 installation instructions during retrofits.
The relay provides current protection of 5A and 1A with 4 digital inputs, 4 digital outputs, 1 analog input, and 1 analog output. It operates at 50/60 Hz and supports a wide voltage range, enabling precise monitoring and control in motor drives, conveyors, pumps, and OEM equipment with integrated diagnostics.
Yes. It supports Modbus TCP over Ethernet RJ-45 and IEC 61850 over Ethernet, along with RS-485 Modbus/DNP3 RTU. This facilitates seamless integration with SCADA, DCS, and multi-vendor control architectures, reducing engineering time and improving data visibility across the plant.
Compliances are listed as 'Contact Manufacturer' in the datasheet, so you should verify CE, SIL, and IP ratings directly with Eaton for your region and application. Confirmation is essential for safety-critical environments and to meet regulatory requirements in power, water, and manufacturing industries.
The device enables centralized monitoring via RS-485 and Ethernet, time synchronization via IRIG-B URTD, and integration with PowerPort-E for diagnostics. These features reduce maintenance cycles, minimize downtime, and improve fault resolution, delivering faster MTBF improvements and a clearer path to total cost of ownership savings.
