Datasheet PR515x605

Signal converters and isolating amplifiers

Issued 3 November 2026

Min/max alarm: 4-20 mA or 0-10 V with two limits and two relays, with OLED display

Article number PR515x605

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

The PR515x605 compares a 4-20 mA or 0-10 V signal with two set limits and switches a separate relay contact for each limit. One module thus provides a low and a high alarm, or a pump that starts at one level and stops at the other. For each relay, the limit, hysteresis and a delay are set on the OLED display, which also shows the current value.

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.
