Datasheet PR505x504

Dimmers for LED and lighting

Issued 4 November 2026

0-10 V to eight PWM channels for LED groups, high-side switched, with Wi-Fi

Article number PR505x504

PR505 module in narrow DIN rail enclosure: SW1, SW2 and SW3 buttons, LEDs and numbered screw terminals

The PR505x504 has eight PWM outputs, high-side switched, that are controlled together by one 0-10 V signal. The minimum and maximum are set per channel, so groups with different LEDs still look the same, or a group switches on only above a certain level. The PWM frequency and dimming rate are set through the Wi-Fi hotspot.

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.
