The relay can monitor any external quantity, such as transformer winding temperature,
bus voltage, battery voltage, station service voltage, transformer tap position, etc., via an
auxiliary current input called the analog input. Any one of the standard transducer output
ranges 0 to 1 mA, 0 to 5 mA, 0 to 10 mA, 0 to 20 mA, or 4 to 20 mA can be connected to the
analog input terminals.
Two independent elements are available for monitoring the analog input level, Analog
Threshold 1 and 2, each having a user programmable name, pickup level, drop out ratio,
and a time delay. For each element, when the measured analog input quantity exceeds
the pickup level for longer than the associated time delay, the relay can be configured to
cause a trip, an alarm, or signal an output contact. The element will drop out only when the
user programmed drop out ratio has been met. There are also two elements which
measure the analog input rate-of-change, Analog In Rate 1 and 2, which operate in a
similar fashion.
