Datasheet PR515x555

Signal converters and isolating amplifiers

Issued 3 November 2026

Frequency or pulses to 0-10 V and 4-20 mA, with OLED display

Article number PR515x555

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

The PR515x555 measures the frequency of a pulse signal on an isolated input and passes it on as 0-10 V and as 4-20 mA. This turns an inductive sensor, a gear pick-up or a flow meter with pulse output into an analogue signal for a PLC or meter. Which frequency corresponds to the start and the end of the output, and the number of pulses per revolution, are set on the OLED display. A version for an input at mains voltage is available on request.

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.
