Maximum number of terminals
Terminals 1 to 6:
Without integrated overvoltage protection
1 Output 1 (passive): supply voltage and signal transmission
2 Output 2 (passive): supply voltage and signal transmission
3 Input (passive): supply voltage and signal transmission

Order code for "Output"
Option A 4-20 mA HART (passive)
1)
Option B 4-20 mA HART (passive)
1)
Option C 4-20 mA HART (passive)
1) 2)
Option D 4-20 mA HART (passive)
1) Output 1 must always be used; output 2 is optional.
2) The integrated overvoltage protection is not used with option D: Terminals 5 and 6 (current input) are not
protected against overvoltage.
