• Motor Health Report
• Statistical information & learned motor data
• Voltage/frequency/power display (M option)
• 4 analog outputs (M option)

The 369 offers a choice of optional monitoring and metering functions including:

• Actual Values
• Metering (Option M)
• Pre-Trip Alarms
• Event Recorder
• Oscillography
• Statistical Data
• Learned Information
• Motor Start Data Logger

Communication

Key Features

• Front Panel RS232 port for programming and troubleshooting
• Optional embedded Ethernet port
• Optional Profibus DP/DPV1 or DeviceNet via dedicated port
• Multiple Protocols – Modbus RTU, Modbus TCP/IP

A front RS232 port is provided for downloading setpoints and interrogating the relay using the EnerVista™ 369.
Three independent rear RS485 ports offer the customer flexibility and performance for their communication network. The 369 can communicate at baud rates up to 19,200 bps using the industry standard Modbus® RTU protocol. Fiber optic (option F) Profibus interface (option P), DeviceNet (option D), and Ethernet (option E) ports are also available. The optional direct connect RJ45 Ethernet port can be used to connect the 369 to 10 Mbps Ethernet networks. The communication system of the 369 is designed to allow simultaneous communication via all ports.

Using Ethernet as the physical media to integrate the 369 to Local or Wide Area Networks replaces a multidrop-wired network (e.g., serial Modbus®), and eliminates expensive leased or dial-up connections, reducing operating costs.
