Eaton EMR-4000-2A1FB0 Motor Relay - 19-300Vdc

Fiber optic communications and time-synced messaging are built in, enabling Modbus or DNP3 RTU over fiber. This reduces electrical noise and allows longer runs between the control panel and remote IO. In practice, users deploy it in distributed motor control applications, conveyors, and packaging lines where clean signaling and fast fault reporting matter. With eight digital inputs, five digital outputs, and four analog outputs, EMR-4000-2A1FB0 delivers rich I/O integration without the need for additional cabinets. The URTD interface, Sensitive Ground Input, and IRIG-B time reference simplify synchronization and protection coordination across multiple drives, enabling tighter safety interlocks and faster fault isolation. This translates to quicker commissioning and lower lifecycle costs in diverse manufacturing environments. Current protection and metering, along with voltage protection and metering, provide real-time visibility and robust motor protection against overloads and abnormal energy usage. The integrated sensing reduces external accessory requirements and simplifies compliance reporting while supporting energy-management initiatives. Conformal coated circuit boards and a rugged build enhance reliability in damp, dusty, or vibration-prone environments typical of industrial floors, shortening maintenance cycles and extending mean time between failures. Zone selective interlocking (1) improves safety and coordination across motor starters, enabling smarter protection schemes and reduced nuisance tripping. When paired with the Eaton E-Series ecosystem, installation becomes more straightforward and maintenance planning is simplified, delivering a faster return on investment.
