F 3331: 8-channel output module
safety-related, applicable up to SIL 3 according to IEC 61508
• resistive or inductive load up to 500 mA (12 W)
• lamp connection up to 4 W
• with integrated safety shutdown, with safe isolation
• with line monitoring
• no output signal at break of the L- supply

Appertaining function block: HB-BLD-3 or HB-BLD-4
The module is automatically tested during operation. The main test routines are:
– Reading back of the output signals. The operating point of the 0-signal read back is
≤ 6.5 V. Up to this value the level of the 0-signal may arise in case of a fault and this
will not be detected
– Switching capability of the test signal and cross-talking (walking-bit test)
Outputs 500 mA, short-circuit proof
Internal voltage drop max. 2 V at 500 mA load
Admissible line resistance (in + out) max. 11
Ω
Undervoltage tripping at ≤ 16 V
Output leakage current max. 350
μA
Output voltage if output is reset max. 1.5 V
Current input WD max. 30 mA
Monitored switching time max. 200
