Analog Inputs and Outputs Use the four configurable analog inputs available in the 469 to measure motor operation related quantities fed to the relay from standard transducers. Each input can be individually set to measure 4-20 mA, 0-20 mA or 0-1 mA transducer signals. The 469 can also be set to issue trip or alarm commands based on signal thresholds. Use the four configurable analog outputs available in the 469 to provide standard transducer signals to local monitoring equipment. The desired output signal must be specified when the relay is ordered, either 4-20 mA, or 0-1 mA. The analog outputs can be configured to provide outputs based on any measured analog value, or any calculated quantity.
Output Relays There are six Form-C output relays available in the 469. Four relays are always non-failsafe and can be selectively assigned to perform trip, or alarm functions. A non-failsafe block start relay is also provided, controlled by protection functions requiring blocking functionality. Loss of control power or 469 internal failures are indicated via the failsafe service relay. The trip and alarm relays can also be configured with latching functionality
