Eaton Specification Sheet - EMR-3000-2B1IB0
EMR-3000-2B1IB0 features four digital inputs and four digital outputs, enabling flexible motor control and simple panel wiring; it reduces wiring complexity while enabling precise logic for start/stop sequences, improving overall control reliability and response times in automation cells. The device supports Modbus/DNP3 RTU over RS-485 and Modbus TCP over Ethernet RJ-45, delivering seamless integration with existing control networks and scalable remote diagnostics to cut downtime and maintenance costs. Conformal coated circuit boards provide enhanced reliability in humid or dusty environments, reducing corrosion risk and extending service life in harsh industrial settings. The wide voltage range of 19–300 VDC and 40–250 VAC (50/60 Hz) supports both DC and AC motor applications, simplifying retrofits and new installations while protecting investments. Current protection and metering enable proactive fault detection and energy management, lowering energy waste and facilitating compliance reporting. Zone selective interlocking (1) improves safety and fault isolation for multi-motor drives, minimizing collateral damage during electrical faults. IRIG-B, Sensitive Ground Input, and URTD Interface options offer precise timing, grounding protection, and advanced time synchronization for test rigs and data logging environments. With standard mounting and Eaton’s robust build quality, installation is straightforward on existing panels and new builds alike, while the included warranty provides peace of mind during commissioning and operation.

FAQs
EMR-3000-2B1IB0 uses standard mounting and compact dimensions (approximately 8.06 in length, 8.62 in height, 6.82 in width) with a weight around 5.82 lb, making replacement and panel integration straightforward. Plan for RS-485 and Ethernet connections in a clean control cabinet, route digital I/O wiring away from high-current cables, and verify clearance for heat dissipation in enclosed panels.
The device supports Modbus/DTMP protocols over RS-485 (RTU) and Modbus over Ethernet (TCP), enabling both fieldbus and LAN communications. This allows remote monitoring, control, and data logging across a plant network, reducing现场 trips and enabling scalable automation architectures without additional gateways.
Yes. The product accepts a wide input range of 19–300 VDC and 40–250 VAC, with a 50/60 Hz frequency rating, enabling control of both DC and AC motors. This flexibility supports retrofits and mixed-motor environments, reducing the need for multiple relay families in a single installation.
It includes current protection and metering to detect overloads and monitor energy usage, and zone selective interlocking to quickly isolate faults within multi-motor configurations. Additional inputs such as IRIG-B timing, Sensitive Ground Input, and URTD Interface enhance safety, timing accuracy, and data integrity in demanding applications like test rigs and critical manufacturing lines.
The EMR-3000-2B1IB0 carries Eaton’s standard warranty terms: one year from installation or 18 months from shipment, whichever occurs first. Compliance details are provided by the manufacturer; confirm regional certifications such as CE marking or IP ratings with Eaton to ensure alignment with local regulations and product variants.
