FAQs
The EMR-4000-2A1EB0 provides eight digital inputs, five digital outputs, and four analog outputs, with no analog inputs. It features 19-300V DC and 40-250V AC operation and offers RS-485 communication over D-Sub with a sensitive ground input option and IRIG-B URTD interface. This IO mix supports integrated motor protection, status signaling, and interlocking in a compact motor relay, simplifying panel wiring and reducing external I/O modules.
Yes, the EMR-4000-2A1EB0 supports PROFIBUS-DP over RS-485 via a D-Sub interface, enabling direct integration with PLCs and field buses. It also supports multiple protection and metering features and offers time-synchronization with IRIG-B and URTD interfaces for coordinated automation. When wiring, plan termination and network address settings to ensure reliable communications.
The recommended workflow uses Eaton PowerPort-E for advanced configuration. Step 4 covers protection, metering, and communication parameter setup before commissioning. This approach reduces onboarding time, minimizes wiring and misconfiguration errors, and provides traceable changes for compliance reviews. It also aligns with Eaton's downloadable training materials and software updates.
The relay offers current protection and metering, voltage protection and metering, and zone selective interlocking. This enables accurate fault detection, energy accounting, and selective tripping in multi-motor circuits. Coupled with conformal coated boards, it delivers reliable operation in harsh environments and simplifies integration with protection schemes.
Warranty is one year from installation or eighteen months from shipment, whichever occurs first per Eaton Selling Policy 25-000. For service, updates, and replacement parts, contact Eaton technical support or your authorized distributor to maintain compatibility and uptime in critical motor applications. Maintaining this line minimizes downtime and ensures ongoing protection.
