●
Application 3: Safety mode SIL3/Cat.3/PLd, 1oo1 (1v1) evaluation.
Possible diagnostic messages, the error causes and possible corrective measures are given
in section "Diagnostic messages (Page 58)".
Current measurement 0/4 to 20 mA, 4-wire transducer
Four process signals can be connected to the F-module in this interconnection variant.
Sensor supply U
V
is provided by the F-module for 4 channels. You can also supply the
sensors by means of an external sensor supply.
