Selling Policy 25-000 - Distribution and Control Products and Services
Modbus TCP or DNP3 TCP/UDP over Ethernet RJ45 enables centralized monitoring and remote diagnostics, reducing panel wiring and accelerating fault isolation. Business impact: faster MTTR and improved asset visibility in SCADA environments; application: machine cells and motor drives integrated into digital factories. 16 digital inputs and 9 digital outputs provide expansive control and status signaling without needing extra I/O modules, streamlining panel layouts and lowering enclosure costs. Business impact: fewer components, simpler wiring; application: motor protection schemes in automation panels. Sensing inputs cover Current Protection and Metering, Power Protection and Metering, Differential Protection, and Voltage Protection and Metering, delivering comprehensive protection and real-time energy data. Business impact: enhanced safety and energy management; application: critical motor feeders and distributed protection schemes. Removable terminals and semi-flush mounting simplify installation and field servicing, reducing downtime during retrofits and upgrades. Business impact: faster commissioning and maintenance; application: retrofit projects and new installations in existing cabinets. Zone selective interlocking (1) improves selective tripping and minimizes fault energy, boosting system availability and reducing equipment stress. Business impact: improved reliability and reduced wear; application: large motor banks in manufacturing lines. Compatibility with the EMR-4000 base relay provides an upgrade path and modular expansion, enabling tailored protection schemes as plant needs evolve. Business impact: scalable protection architecture; application: expanding motor protection coverage without replacing entire systems.
