Key Features
Protection & Control
The 489 Generator Protection System provides comprehensive protection, metering, and monitoring of small to medium sized synchronous or induction generators operating at 25, 50 or 60 Hz. The 489 is ideally suited for primary or backup generator protection as well as for use in cogeneration applications. Protection features found in the 489 include:
Key Features
Monitoring & Control
Advanced Automation
The 489 offers a multitude of different analog and digital inputs and outputs to allow the 489 to be seamlessly integrated into most generator automation schemes.
Outputs Relays
The 489 provides six output contacts for the purpose of controlling or signaling other devices and operations personnel. Protection elements can be configured to control the Trip contact, the Alarm contact, or the 3 Auxiliary contacts whenever the element operates. The status of each of these contact are also displayed on LEDs found on the relays front panel.
Digital Inputs
Eight digital inputs are available for monitoring the status of external contacts, tachometers, or control switches. With these inputs, the relay can identify the status of the associated breakers and receive commands from operational staff such as controlling the output relays, resetting the thermal limits, or triggering a waveform capture.
RTD Inputs
Twelve RTD inputs allow the 489 to monitor both the generator stator and bearing temperature. A built in voting feature adds additional security by ensuring that two RTDs monitoring the same device both detect the overtemperature condition before tripping the generator offline.
Analog Inputs
Four analog inputs are available for providing protection and monitoring of generator bearing vibration. The analog inputs are field programmable to measure transducer signals that operator over a range of 0 to 1 mA, 0 to 20 mA, or 4 to 20 mA.
Analog Outputs
Four analog outputs are available for signaling the value of measured analog quantities to external process control devices such as PLCs. The analog outputs can be ordered to operate over a 4 to 20mA range or a 0 to 1mA range and can be configured to signal a representation of most analog quantities measured by the 489 including currents, voltages, frequency.
Key Features
Advanced Communications
The 489 provides advanced communications technologies for remote data and engineering access, making it easy and flexible to use and integrate into new or existing monitoring and control systems. Multiple communication ports are available including a front panel RS232 serial port for easy local computer access, two RS485 serial ports and a 10Mbps copper Ethernet port that provide direct integration in most communications architectures.
