4-20 mA current output
(see also Fig. 7 and diagram 7):
Required to operate the external power supply.
Permissible range: 9…32 V d.c. / 150…50 mA
Galvanically isolated
The 4…20 mA d.c. output signal corresponds to an actual discharge current of 0…40 Arms, that
is 0.4 mA / 1 A.
An alarm value of 22.8 mA is transmitted for remotely signalling a failure mode at the device
which requires on-site operator intervention.
