IUC-7X-PWM: Isolated PWM Converter               specsheet 

Features: DIN-Rail Mounted (small size) Wide Input PWM Range (from 5Hz to 3KHz) Industry Standard Output: 4-20 mA, 1-5 VDC, and more.... Easy Field Calibration (Typ. calibration time < 2 min. using handheld meter only) Microprocessor Controlled for High Accuracy 24 VDC Supply for Open Collector  Input or Dry Contact Input. Power: 24 VDC High Noise Rejection CSA and NRTL Approved

Function:
The IUC-7X-FRX is a microprocessor controlled PWM to analog output converter/isolator that is easily field configurable to and PWM input from 0-5 Hz to 0-2 KHz. 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 lettle effort. All that is required to change the calibration settings is a voltmeter and a small screwdriver.

The IUC-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.
