F 3348
F 3348: 8-channel output module
safety-related, applicable up to SIL 3 according to IEC 61508
• Output voltage 48 VDC
• resistive load or inductive load up to 500 mA
• lamp connection up to 4 W
• with integrated safety shutdown, with safe isolation

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 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
Operating point for
