*Refer to the front of the Optocoupler section of the current catalog for a more detailed description of IEC/EN/DIN EN 60747‑5‑2 and other prod‑
uct safety regulations.
Note: Optocouplers providing safe electrical separation per IEC/EN/DIN EN 60747‑5‑2 do so only within the safety‑limiting values to which they
are qualied. Protective cut‑out switches must be used to ensure that the safety limits are not exceeded.
