Selling Policy 25-000 - Distribution and Control Products and Services
The EMR-5000-2B0KA0 expands protection logic with extensive I/O: eight digital inputs and nine digital outputs allow complex interlocking and signaling schemes, improving fault visibility and allowing faster decision-making in high-demand environments. With two analog inputs and two analog outputs plus current and voltage protection and metering, operators gain precise monitoring, enabling measurable energy savings and better asset utilization. The semi-flush mounting and removable terminals simplify installation, reduce commissioning time, and ease field wiring changes during maintenance or upgrades. Compatibility with the EMR-4000 base relay provides a proven upgrade path for legacy protection schemes while preserving common tooling and spare parts. Fiber-optic Ethernet communications (IEC 61850) and Modbus/DNP3 TCP support future-proofs control architecture and simplifies integration with SCADA and energy management systems. Zone selective interlocking (ZSI) and a 50/60 Hz operating bandwidth enable consistent protection coordination across diverse motor fleets, delivering reliability and uptime gains in manufacturing or process environments. The 19-300 Vdc and 40-250 Vac voltage range supports a wide variety of motor feeders, reducing inventory complexity and enabling cross-site standardization of protection settings.
