FAQs
The EMR-3000-2A1BB0 is designed for standard mounting in motor-control panels. Begin by locating the device in a clean, ventilated enclosure, connect the RS-485 Modbus line for industrial communication, and wire the four digital inputs and four digital outputs to your control logic, ensuring proper grounding. Use the URTD interface or IRIG‑B options as needed for synchronization or ground management. Verify voltage ranges (19–300Vdc/40–250Vac) match your motor and power supply, and secure conformal-coated boards to withstand environmental exposure.
The relay supports phase currents of 5A and 1A, with a voltage range of 19–300Vdc and 40–250Vac at 50/60 Hz. It provides one analog output and four digital outputs alongside four digital inputs. This combination enables local monitoring and control, motor protection and metering, and reliable remote signaling over RS-485 using Modbus or DNP3 RTU protocols.
Yes, the EMR-3000-2A1BB0 includes conformal-coated circuit boards designed for harsh environments, a wide operating voltage range, and protective I/O features like IRIG-B and URTD interfaces. Its robust physical footprint and 5A/1A current ratings make it suitable for industrial motor control panels in manufacturing, processing, and material handling facilities where reliability and uptime are critical.
Compliance details for EMR-3000-2A1BB0 are provided by the manufacturer. Typical considerations in industrial motor relays include CE safety, IP-based environmental protection, and SIL/PL safety certs; however, confirm the exact certifications and tests with Eaton to ensure alignment with your regulatory requirements and risk management framework.
The product carries Eaton’s warranty policy of one year from installation or eighteen months from shipment, whichever occurs first. This warranty, combined with the relay’s reliability, diagnostic capabilities, and remote monitoring options via RS-485, supports reduced maintenance trips, lower downtime, and faster fault resolution—contributing to a favorable total cost of ownership in automated motor-driven systems.
