F 3334: 4-Fold Output Module (F3334)

The F 3334 is a safety-related, 4-fold output module designed to handle both resistive and inductive loads up to 2 A (48 W) and lamp connections up to 25 W. This module includes integrated safety shutdown, safe isolation, and line monitoring, ensuring no output signal is present if the L- supply line breaks. Suitable for requirement classes AK 1 to AK 6, the F 3334 offers high reliability and enhanced safety features.
