Optron IL250 – optical isolatorIL250 is an optical isolator (optron) with a phototransistor output, designed for AC and DC signal transmission, ensuring galvanic isolation between input and output circuits. The component is widely used in control, measurement, automation, and industrial electronic systems where reliable electrical isolation is required.

The dual-sided LED input allows the optocoupler to be used for both AC and DC signals without additional smoothing.
