F 3333: 4-channel output module
safety-related, applicable up to SIL 3 according to IEC 61508
• resistive load or inductive load up to 2 A (48 W)
• lamp connection up to 25 W
• with integrated safety shutdown, with safe isolation
• no output signal at 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 the test signal and cross-talking (walking-bit test)
Outputs 2 A, short-circuit-proof
Internal voltage drop max. 2 V at 2 A load
Admissible line resistance (in + out) max. 3.6
Ω
Undervoltage tripping at ≤ 16 V
Operating point for short circuit current 2.6 ... 5 A
Output leakage current max. 550
μA
Output voltage if output is reset max. 1.5 V
Monitored switching time max. 200
