FAQs
Installations with EMR-4000 bases are streamlined by using the same form factor and removable terminals. The projection mounting option simplifies panel fitment, while the 2 analog in, 2 analog out, 8 digital in, and 9 digital out channels remain accessible for quick wiring. This reduces commissioning time and minimizes downtime during retrofits.
The EMR-5000-2B1KA1 operates from 19–300 Vdc or 40–250 Vac at 50/60 Hz. It offers 2 analog inputs, 2 analog outputs, 8 digital inputs, and 9 digital outputs, with URTD, IRIG-B, and Sensitive Ground Input as I/O options. It also supports IEC 61850 and Modbus/DNP3 communication over fiber networks.
Yes. The unit provides IEC 61850 communication over LC duplex fiber optic Ethernet, enabling high-speed, networked protection and interoperability with other IEC 61850 devices. This makes it well-suited for modern substations, plant-wide protection schemes, and integrated control architectures.
The data does not explicitly list CE, SIL, or IP certifications. It notes IEC 61850 compatibility over fiber and Modbus/DNP3 TCP over fiber, along with standard Eaton warranty terms. For definitive certification details, consult Eaton or the official specification sheet before deployment in regulated environments.
The EMR-5000-2B1KA1 reduces wiring complexity with removable terminals and extensive I/O, speeding installation and commissioning. Fiber Ethernet support enables remote diagnostics and faster fault isolation, which can lower downtime and maintenance costs while improving system uptime and long-term total cost of ownership.
