Conductivity Switch Amplifier
Описание
1-channel signal conditioner, 115 V AC supply, Level sensing input, Adjustable range 1 kΩ .. 150 kΩ, Relay contact output, Fault relay contact output, Adjustable time delay up to 10 s, Minimum/maximum control, Line fault detection (LFD)pa. 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. If LB monitoring is selected, output II serves as the fault signal output; otherwise, it will follow the function of output I.
