Product description

Level monitoring and control for conductive liquids and powders, e.g. maximum
and minimum filling levels, overfilling and protection against dry running
Monitoring and control of the mixing ratio of conductive liquids
General resistance monitoring tasks, e.g. limit temperature detection with PTC
Contact protection relay with time delay

According to IEC/EN 60 255-1
3 probe connections for 2-point and 1-point level control
Also for use as moisture detector
High interference resistance of the Measuring Circuit,
which is isolated from the mains
Max. wire length to the probes: 3000 m
Large setting range: 2 ... 450 kΩ this
permits differentiation between fluid and foam
Separately adjustable response and release time delay
0.2 ... 20 s for MIN- and MAX-level
Programmable for:
- 2 separate controllable output relays for MIN and MAX level
- common controlled output relays for 2-point hysteresis level control
- open circuit operation
- closed circuit operation
Measuring Circuit for probes works with internally generated AC voltage
(approx. 30 Hz), electrolytic behaviour does not occur in the liquid
For auxiliary voltages of 24 ... 415 V AC or 24 V DC
LEDs for operation and state of contact
2 changeover relays with 1 changeover contact each
IL 9151 and SL 9151 with safe separation according to
IEC/EN 61 140, IEC/EN 60 947-1
