Conductivity Switch Amplifier KFA5-ER-1.W.LB

• 1-channel er
• 115 V AC supply
• Level sensing input
• Adjustable range 1 k&Omega, ... 150 k&Omega,
• Relay output
• Fault relay output
• Adjustable time delay up to 10 s
• Minimum/maximum control
• t detection (LFD)

This er 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 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 ture 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 therwise, it will follow the function of output I. Product Description
