Advanced communications allows easy integration into process and electrical control systems for smoother asset monitoring & control.
Quality & Reliability
• IPC A-610-E Class 3 manufacturing standards to ensure device quality and reliability
• Environmental board level stress screening and full functional testing
• Standard harsh environmental coating for added reliability
Advanced Motor Monitoring & Diagnostics
Integrated, cost effective monitoring and diagnostic features that leverage existing relay data without the need for additional devices or sensors to detect electrical, thermal or mechanical abnormalities before they become critical motor failures.
Electrical
Abnormalities
If undetected, insulation failure can evolve into phase or ground faults, causing equipment damage or loss, and significant unplanned downtime. The 869’s advanced motor monitoring and trending capabilities provide identification of critical electrical conditions.
Thermal
Abnormalities
The 869 continuously and proactively monitors the motor for Thermal Capacity Used (TCU) to provide early warning of thermal stresses.
Mechanical
Abnormalities
Without the need for additional sensors or probes, the 869 utilizes GE's patented Electrical Signature Analysis (ESA) / Motor Current Signature Analysis (MCSA) to identify mechanical abnormalities in the motor.
