Datasheet PR515x601 · 0-5 V to relay, adjustable limit and hysteresis, with OLED display

PR515 module in horizontal DIN rail enclosure, front view with pluggable screw terminals

The PR515x601 compares a 0-5 V signal, for example from a pressure sensor or ratiometric sensor, with a set limit and switches a relay contact when it is exceeded. The hysteresis prevents the relay from chattering around the limit. You choose whether the relay switches on above or below the limit. The OLED display shows the current value and the relay state.

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.
