Datasheet PR515x501

Signal converters and isolating amplifiers

Issued 3 November 2026

PT100 or PT1000 to 4-20 mA, galvanically isolated, with OLED display

Article number PR515x501

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

The PR515x501 measures the temperature with a PT100 or PT1000 sensor in a 2-, 3- or 4-wire connection and passes it on as 4-20 mA. The sensor input is galvanically isolated from the supply and the output, so a sensor in contact with an earthed part of the installation does not cause a ground loop. The sensor type and the temperature at 4 and at 20 mA 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.
