Analog modules
9.3 SM 336; F-AI 6 x 0/4 ... 20 mA HART
Fail-safe signal modules
250 Installation and Operating Manual, 01/2010, A5E00085586-10
For information about the Zener diodes, refer to chapter "Calculation of the residual supply
voltage at the transducer (Page 239)".
WARNING
To achieve SIL3/Cat.4/PLe using this wiring, you must use a suitably qualified sensor.
Note
You can supply the two F-SMs from two power supply units. If you use two power supply
units, the two grounds on the F-SMs will have to be connected with each other.
