FAQs
The EMR-4000-2A0DB1 supports URTD Interface IRIG-B and PROFIBUS-DP over fiber optic ST, which simplifies integration with existing control networks. Ensure your PLC or distributed I/O system can address the 8 digital inputs, 5 digital outputs, and 4 analog outputs and verify cable and connector integrity in your enclosure.
This motor relay handles phase currents of 5A and 1A with operating voltage ranges from 19 to 300 VDC and 40 to 250 VAC. These ranges accommodate diverse drive configurations, enabling safe switching for mid-to-large motor loads while maintaining protection and metering functionality.
The EMR-4000-2A0DB1 integrates sensing inputs for voltage, current, and protection and metering, alongside zone selective interlocking. This enables precise fault detection, energy monitoring, and targeted isolation, reducing unplanned downtime and enabling proactive maintenance in industrial drives.
Compliance details are provided by the manufacturer. The unit features conformal coating for harsh environments and built-in protection/metering capabilities, but verify CE, SIL, IP or other regulatory certifications directly with Eaton to match your project requirements.
Maintenance focuses on periodic inspection of fiber optic connections, relay contacts, and protection circuits. The device’s conformal coating and robust IP-like protections help minimize dust and moisture ingress. ROI benefits arise from reduced downtime, extended motor life, and easier network integration, especially in high-availability manufacturing lines.
