FAQs
The EMR-4000-2A0EB0 integrates motor protection, metering, and I/O in a compact unit, reducing panel space and wiring. Ensure correct RS-485 or PROFIBUS-DP wiring, verify I/O counts (8 digital inputs, 5 digital outputs, 4 analog outputs), and confirm enclosure fit for the target cabinet. Consider conformal coating in harsh environments to maximize reliability.
It provides voltage, current, and power protection with metering capabilities, enabling real-time monitoring and protective tripping. This supports safer startup/shutdown sequences and accurate energy accounting. The device’s 5A/1A phase current handling and 0 analog inputs are complemented by multi-channel I/O for integrated protection logic on motor-driven systems.
Yes. The unit supports PROFIBUS-DP over D-Sub / RS-485, enabling seamless integration into established automation networks. It also features IRIG-B interface options for time synchronization and advanced control scenarios, making it suitable for centralized protection schemes in complex plants.
Certification specifics such as CE, SIL, or IP ratings depend on configuration and regional requirements. The datasheet notes that compliances should be confirmed with the manufacturer. Contact Eaton to obtain the exact regulatory approvals for your installation site and industry segment.
The unit’s integrated protection and metering reduce downtime and maintenance intervals by proactively detecting faults. The warranty covers one year from installation or 18 months from shipment, whichever comes first, which supports a favorable total cost of ownership. Its robust build and conformal coating further lower lifecycle maintenance costs in tough environments.
