Article number PR515x522

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

The PR515x522 has a universal analogue input with a 16-bit converter, galvanically isolated from the supply and the output. The signal type and range are selected on the OLED display, so the same module suits different sensors and transmitters. The output is 4-20 mA; start and end are freely adjustable, also for a small part of the input range.

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.
