a
This specification is relevant only if the Ext. voltage supply is selected under the "Contact" point in the
Configuration. Sensors and transmitters should be supplied from voltage supply outputs on the JUMO
AQUIS touch S. An externally supplied voltage signal must not have a voltage over 28 V.
b
All digital inputs IN 1 to 3 are suitable for connecting proximity switches. Recommended
types are: Wachendorff P2C2B1208NO3A2 and Balluff BES M12EG-PSC80F-BP03.
c
Binary inputs IN 2 and IN 3 can be used for impeller flow-through sensors (water meters) or
magnetic-inductive flow-through meters (square-wave signal), for example. The input frequency depends
on the configured measurement principle in the flow function.
