GND = Ground; SPST = Single Pole Single Throw
2) In options 1, 4, and 5, the alarm relay is N.O. (terminals 6 and 7).
In options 2 and 3, the alarm relay is N.O. (terminals 6 and 7) or N.C. (ter-
minals 7 and 8).
3) The auxiliary output is a N.O. (SPST) relay. The auxiliary relay may act in
parallel with the alarm relay to activate another external device or it may
provide a warning signal, depending on the function configuration.
4) Available with the HART protocol
0-20 mA is ‘sink’ in option 1 and ‘source’ in option 2 and 3. The maximum
permitted load is 600
Ω.
In wiring option 1, link terminals 1 and 8 to change the mA output to ‘source’.
