522-Opto-coupler

Description

New, small Opto-Coupler generation according EN50020. The potted Opto-Couplers are perfectly suitable for the galvanic separation of intrinsically safe and non- intrinsically safe circuits. Transistor technology guarantees clearly defined, clean switching status; with transmission frequencies up to 50kHz - universally applicable. The maximum peak voltage for electric circuits amounts to ` ia` 375 V. They are approved according to ATEX and DIN EN 50020.
