Datasheet PR515x551

Valve and motor drivers (PWM)

Issued 3 November 2026

0-5 V to PWM, high-side or low-side switched, with OLED display

Article number PR515x551

PR515 module board from above: OLED display, UP, OK and DWN buttons, relay, USB-C port and terminals 1 to 22

The PR515x551 converts a 0-5 V voltage into a PWM signal: as delivered, 0 V gives 0 % and 5 V 100 %. The output switches high-side or low-side, selected on the OLED display. The input range, the output minimum and maximum, the PWM frequency and the ramp are also set there. This lets you drive a valve, lamp or small motor from a sensor or potentiometer with a 0-5 V output.

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.
