Any frequency value can be assigned to the initial or final analogue value, e.g. for
the 4...20 mA standard signal:
input frequency 200 Hz = 4 mA and input frequency 1.2 kHz = 20 mA.
The value of the output signal changes either in proportion or out of proportion
with the value of the input frequency.
The monitor has a "Teach" function which allows to measure current input fre-
quencies and to assign them to the parameters for initial and final values.
Moreover the FA-1 monitor monitors whether the input frequency is above or be-
low a switching threshold and switches the output according to the parameters
set. The switch point can also be set via a Teach function.

The FA-1 monitor only has one channel. By means of an electrical connec-
tion of the output of two or several units to achieve a redundant circuit, they
can also be used for safety tasks. The applicable technical standards must be ad-
hered to.
