F 3330: 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 load up to 4 W
• with integrated safety shutdown, with safe isolation
• no output signal with break of the L- supply
Figure 1: Block diagram and front cable plug
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).
