Conductivity Switch Amplifier
Description
This signal conditioner provides the AC measuring voltage for the level sensing electrodes. 2-channel signal conditioner, 230 V AC supply, Level sensing input, Adjustable range 1 kΩ .. 150 kΩ, Relay contact output, Adjustable time delay up to 10 s, Minimum/maximum control, Line fault detection (LFD)pa. 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.
