The NTC-7X-PWM is a microprocessor controlled PWM to analog output converter that is easily field configurable to any PWM input from 0-5Hz to 0-3KHz. Adjustments to the input settings can be made while the instrument  is operating. This flexibility combined with easy field calibration allows for the fine tuning of a process on site with little effort. All that is required to change the calibration settings is a voltmeter and a small screwdriver.

The NTC-7X-PWM operates over a wide duty cycle range of at least 5% to 95%. The duty cycle range depends on the PWM frequency. The lower the PWM frequency the wider the duty cycle range that can be converted.
