In one device you can choose the following configurations:

• - 1. one-level swotch of conductive liquids ( by connecting H and D)
• - 2. two-level switch of conductive liquids ! One-state device monitors one level, two-state device monitors two levels (switches on one level and switches off  on another level)
• - Choice of function PUMP UP, PUMP DOWN
• - Adjustable time delay on the output (0.5 - 10 s)
• - Sensitivity adjustable by a potentiometer (5-100 kÙ)
• - Measuring frequency 10Hz prevents polarization of liquid and raising oxidation of measuring probes
• - Galvanically separated supply voltage UNI 24.. 240 VAC/DC
• - Output contact 1xchangeover/SPDT  8A/250V AC1
• - 1-module type, mounting onto a  DIN rail
