Datasheet PR515x552

Signal converters and isolating amplifiers

Issued 3 November 2026

PWM to 0-5 V, galvanically isolated input, with OLED display

Article number PR515x552

PR515 module in horizontal DIN rail enclosure, front three-quarter view, with screw terminals and USB-C port

The PR515x552 measures the duty cycle of a PWM signal and converts it into a 0-5 V voltage: as delivered, 0 % gives 0 V and 100 % 5 V. The input is galvanically isolated with an optocoupler, so the PWM signal may have a different ground from the output. Start and end of input and output and the filtering are set on the OLED display.

Price on request. Supplied in series, from 10 units per item. Not in stock? Then we build your series. One or a few units only as a trial, for a company with a series in sight.
