'ADJUSTABLE AND PROGRAMMABLE' LEVEL CONTROL UNIT
FOR CONDUCTIVE LIQUIDS. (DIN RAIL MOUNTING).
EV is a relay for the control of conductive liquid levels, suitable for wells, cisterns, tanks (even under pressure) and rainwater applications. It uses electrodes called “probes”, powered at low voltage, to detect current flow in the liquid and activate the relay with fast response times. It allows monitoring the level with two probes for a single level (MAX and COM) or with three probes for a range between a minimum and a maximum (MIN, MAX, and COM).
EV is ideal for confined and deep spaces thanks to: probes without mechanical movements and not very sensitive to the typical humidity of wells and tanks, with low loss power cables over long distances. To adapt to different liquid conductivities, EV has adjustable sensitivity and performance that allows a distance of 1000 meters from the probes, even with maximum sensitivity. It’s possible to set a relay activation delay from 0 to 16 seconds and select the relay operation mode (filling/emptying). The 3-module DIN version (3M) offers a relay output with two changeover contacts, operating at 230V. Additionally, variants designed for different supply voltages: 24Vac/117Vac/230Vac are available.

Applications
EV is primarily used in the following contexts:
- Tanks and Containers (even under pressure): monitoring and managing water levels in storage tanks.
- Basins: Monitoring water levels in basins or ponds.
- Wells: Monitoring and controlling water levels in wells.
- Rainwater Accumulation: monitoring and controlling water levels in rainwater accumulations.
Features
- DIN Rail Mounting: with standard dimensions of 2DIN and 3DIN.
- For confined and deep spaces: thanks to its compact design and the fact that the probes do not require mechanical movements.
- Adjustable Sensitivity: EV allows the adjustment of this feature.
- Power Variants: EV is available in variants designed for different supply voltages, including 24Vac, 117Vac, and 230Vac.
- High Operational Safety: The proposed probes are not very sensitive to the typical humidity conditions of wells and tanks, offering high operational safety.
- Quick Response: EV offers a quick response with a timely response time of the liquid level.
- Multiple Applications: EV finds application in a variety of contexts, including tanks, basins, wells, and rainwater accumulations.
