489 Generator Protection System 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...
