NTC-7X-FRT: Non-Isolated Frequency Converter with Alarm Trip
Function:
The NTC-7X-FRT is a microprocessor controlled Frequency to analog output converter that is easily
field configurable to any frequency input from 0-10 Hz to 0-10 KHz. It has a single form "C" contact
that has individual setpoint, deadband and delay adjustments. In addition, there is an analog output
that converts the input frequency to any one of several standard outputs.
The Setpoint and Deadband are adjustable from 0-100 % of the calibrated input frequency. The deadband
is an absolute type deadband, meaning that it is always linked to the setpoint. Once it is set to a certain
value, it need not be adjusted again if the setpoint is re-adjusted. The delay function adds an optional
delay on the relay trip function of 0-60 sec. This is helpful in eliminating false alarms.
