*Refer to the front of the Optocoupler section of the current catalog for a more detailed description of VDE 0884 and other product

safety regulations.

Note:

Optocouplers providing safe electrical separation per VDE 0884 do so only within the safety-limiting values to which they are

qualified. Protective cut-out switches must be used to ensure that the safety limits are not exceeded.
