Features
- According to IEC/EN 60255-1
- 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 61140, IEC/EN 60947-1
- Devices available in 3 enclosure versions:
IL 9151: Depth 59 mm, with terminals at the bottom for installation systems and industrial distribution systems according to DIN 43880
SL 9151, MK 9151N: Depth 98 mm, with terminals at the top for cabinets with mounting plate and cable duct - IL/SL 9151: 35 mm width
MK 9151N: 22.5 mm width
