NTC-7X-FRT Non-Isolated Frequency Converter & Trip

Brand: Pribusin, Inc

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.
