LEVEL CONTROL UNIT FOR CONDUCTIVE LIQUIDS.
(MOUNTABLE ON DIN RAIL WITH UNDECAL BASE-11 PIN)
Z11 is a relay for the level control of conductive liquids, ideal for wells, tanks, reservoirs (including pressurized ones)… including applications with rainwater. It uses electrodes referred to as “probes”, which operate on low voltage. When these probes come in contact with the liquid, they detect a current flow and activate the relay. This all happens with very fast response times. The solution allows monitoring the level in two ways: using two probes for a single level (MAX and COM) or three probes for a range between a minimum and a maximum (MIN, MAX, and COM).
Z11 is perfect for narrow and deep spaces since the probes don’t require mechanical movements and the cables for the probes have low loss even over long distances. Moreover, the probes are appropriately insensitive to the typical humidity found in wells and tanks. Z11 has a compact design for easy installation even in limited spaces (79x35x88 mm -2 DIN modules) and is available in various sensitivities (NS, AS, SR) and in different power supply voltages 24-48Vac and 117-230Vac (dual voltage).
Z11 is different from Z8 in terms of handling dual-voltage and for the type of combinable base.

Applications
Z11 is mainly applied in the following contexts:
- Tanks and Containers (including pressurized): Monitoring and management of the water level in storage tanks.
- Basins: Monitoring of water levels in basins or ponds.
- Wells: Monitoring and control of the water levels in wells.
- Rainwater Accumulation: Monitoring and control of water levels in rainwater accumulations.
Features
- Adaptability: Z11 is suitable for narrow and deep spaces due to its compact design and the fact that the probes don’t require mechanical movements.
- Various Sensitivity Options: Z11 is available in different sensitivity options: normal, high for low conductivity liquids like rainwater, and adjustable.
- Power Variants: Z11 is available in versions designed for different power supply voltages, including 24/48Vac and 117/230Vac at 50 ÷ 60 Hz.
- Compact Design: With dimensions of 79x35x88 mm (2 DIN modules), Z11 has a compact design that makes installation easier even in limited spaces.
- Quick Response: Z11 offers a quick response with a response time of 100 ms, ensuring timely liquid level control.
- Broad Applications: Z11 is applicable in a variety of contexts, including tanks, basins, wells, and rainwater accumulations.
- Cabling Distance: The NS version offers a maximum distance between the probe and the relay of up to 1000 meters.
- Light Indicator: Z11 has a status light indicator, simplifying the visual check of operations.
