3.2 Principle of operation
The VEGATOR 121 is a single channel controller for level detection of
limit switches with 8/16 mA interface. Via the integrated relay simple
control tasks can be solved. Typical applications are monitoring func-
tions such as overfill or dry run protection, Optionally an additional
second relay can be ordered. Via a DIL switch the function of the
second relay can be determined. It can be configured as fail safe relay
or as second level relay.
The VEGATOR 121 controller powers connected sensors and simul-
taneously processes their measuring signals.
When the medium reaches the switching point of the sensor, the sen-
sor current changes. This is measured and evaluated by VEGATOR
121. The change causes the output relays to switch according to the
set operating mode.
