Apie prekę
This signal conditioner provides the AC measuring voltage for the level sensing electrodes.
Once the measured medium reaches the electrodes, the unit reacts by energizing a form C changeover relay contact.
The module is voltage and temperature stabilized and guarantees a defined switching characteristic.
It can be used for on/off control or minimum/maximum control. A signal delay feature is available and is adjustable between 0.5 s and 10 s.
This module can also monitor the field circuit for lead breakage (LB). LB is indicated by a red LED. This function can be deactivated with DIP switches.
