UA-7D-FRX Frequency Alarm Trip
Brand: Pribusin, IncThe UA-7D-FRX is a microprocessor controlled frequency alarm trip. It is easily field configurable to operate in a large number of different modes. Each relay contact output is individually configurable to the following modes of operation: High/Low Trip , Normally Energized / De-energized. Additionally, both relays operate from the same input to give two levels of alarm for a single input.
A delay feature allows a 0-60 sec. adjustable ON delay to be added to the trip function in order to screen out intermittent and erroneous alarms. If the delay function is activated, the input must be greater than the setpoint for the time specified by the delay before the relay will activate. There is also a combined ON and OFF delay function which, in addition to delaying the relay 'turn-on' time, delays the relay 'turn-off' time.
