5094-IB16S and
5094-IB16SXT Module
Wiring Diagrams
The following wiring diagrams show the input modules in Safety Mode and
Safety Pulse Mode.
Figure 28 - 5094-IB16S Module - SIL 3, PLc, Cat. 2 in Safety Pulse Mode or Safety Mode
Figure 29 - 5094-IB16S Module - SIL 3, PLc, Cat. 2 in Safety Mode
Test Output Association with Safety Input:
TO_0: SI_0, SI_8
TO_1: SI_1, SI_9
TO_2: SI_2, SI_10
TO_3: SI_3, SI_11
TO_4: SI_4, SI_12
TO_5: SI_5, SI_13
TO_6: SI_6, SI_14
TO_7: SI_7, SI_15
Note: In Safety Pulse mode, if external wiring short of 2 Safety inputs from the same Test Output point, the short
circuit is not detectable. Hence, in Dual Channel mode, use 2 Safety Inputs from different Test Output points.
