1 SmartSense wire
2 Maximum input
3 Not for rail-mount transmitter
4 Differential value > 5 Ω or select "Sensor break = None"
DANGER!
"Isolation input/output/PC" as shown in section "Technical data" on page 36 only shows the
signal isolation. This is not an intrinsically safe galvanic isolation, which can be interpreted as an
isolating barrier. Therefore particular care should be applied when selecting the barriers for the
TT 30 R Ex.
