FAQs
This EMR-3000-2B0GB1 supports 4 digital inputs, 4 digital outputs, D-Sub RS-485, and IRIG-B options, making it straightforward to retrofit into Eaton E-Series based systems or existing motor control panels. Its projection mounting simplifies rack or enclosure installation, while the wide 19–300 Vdc / 40–250 Vac range reduces the need for multiple power rails. Ensure wiring adheres to your panel’s enclosure standards and consult the URTD interface documentation for network topology.
The device provides 5A, 1A current protection and metering via its sensing inputs, plus 4 digital I/O lines for local control. Its 50/60 Hz specification supports common industrial mains, and the IRIG-B interface enables precise timing synchronization. These features translate to reliable fault detection, coordinated motor sequencing, and reduced downtime in automated processes.
Best-fit applications include motor protection and sequencing in manufacturing lines, pumps and fans in process automation, and conveyors with distributed control needs. The combination of RS-485 communication, URTD/IRIG-B timing, and conformal coating supports harsh environments, making it ideal for outdoor installations, chemical plants, and energy-intensive facilities requiring robust diagnostics and easy integration.
The product page lists Compliances as 'Contact Manufacturer,' so formal certifications (for example CE, UL, SIL, or IP ratings) are not publicly specified here. For project-specific regulatory requirements, contact Eaton directly to obtain the latest certification documentation and any regional compliance statements relevant to your installation site.
By consolidating motor protection, timing, and I/O into a single relay with flexible power inputs and robust interfaces, maintenance cycles are simplified and spare parts management is reduced. The conformal coating and rugged interfaces improve mean time between failures in challenging environments, which translates to lower maintenance costs, fewer panel upgrades, and faster project commissioning.
