F 3331 HIMA 8 Channel Safety-Related Output Module

Module Description: The F 3331 module is engineered to provide reliable outputs for safety-critical applications. It supports resistive loads or inductive loads up to 500 mA (12 W), as well as lamp connections up to 4 W. Equipped with integrated safety shutdown and safe isolation features, along with line monitoring capabilities, it ensures dependable operation. It conforms to requirement class AK 1 to 6.

Automatic Test Routines:

• Reading Back of Output Signals: The 0 signal's operating point during readback is ≤ 6.5 V. Up to this value, the 0 signal's level may increase in the event of a fault without detection.
• Switching Capability and Cross-Talking: Ensures proper functionality of test signals and minimizes cross-talk (walking-bittest).
• Line Monitoring: Monitors output lines for abnormalities.
