FAQs
Plan for the projection-mountable enclosure with a footprint of 8.06 in deep, 8.7 in high, and 9.72 in wide, weighing about 9.259 lb. Provide eight digital inputs, five current paths (5A/1A), four digital outputs, and four analog outputs. Use the IRIG-B URTD interface plus PROFIBUS-DP over fiber for remote diagnostics and timing. Verify panel clearance, heat dissipation, and cable routing to minimize EMI and ensure reliable operation.
This model offers current and voltage protection with metering for power protection, plus zone-selective interlocking (ZSI). It provides 8 digital inputs, 5A/1A phase current capability, 4 digital outputs, and 4 analog outputs. Communication options include PROFIBUS-DP over fiber optic ST and IRIG-B URTD interface, enabling synchronized, noise-immune control in demanding environments.
Yes. The 8 DI/5A-1A phase capability, 4 DO, and 4 AO support complex motor-protection schemes, metering, and remote signaling. ZSI enhances selective tripping, reducing broader system outages. The fiber-based Profibus-DP connection improves reliability in electrically noisy factory floors, making it suitable for conveyors, pumps, and critical process equipment in OEM and integration projects.
Compliances are flagged as manufacturer-specific; consult Eaton for the exact certifications on EMR-4000-2A0DA1. In practice, plan for common industrial standards such as CE markings and IP-rated enclosures, and verify UL/CSA where required by your region and application. Always confirm with the supplier before deployment to ensure regulatory alignment and safety compliance.
The product carries Eaton’s warranty policy: one year from installation or eighteen months from shipment, whichever occurs first. This reduces maintenance risk and supports long-term budgeting. The integrated I/O, reduced wiring, and robust fieldbus options can shorten commissioning, improve uptime, and lower lifecycle costs in capital projects and service contracts.
