Carlo Gavazzi Group SV215115 Dual Level Relay

Carlo Gavazzi SV215115 Dual Level Relay is a conductive-liquid level-control device that uses two electrodes to sense liquid presence and switches two independent circuits through a DPDT relay output; as part of the SV1xx/SV2xx level-control family, it provides two level relays for max and min control and is powered from 115 VAC at 45–65 Hz. It supports liquids with conductivity roughly 3.5 kΩ to 25 kΩ and relies on separate electrodes to detect the high and low thresholds, enabling two-level operation with the relays energizing for the detected level conditions. The unit weighs about 0.45 lb (roughly 0.20 kg). This model is listed as discontinued by the manufacturer in retailer catalogs, while Carlo Gavazzi’s product family pages affirm the two-level conductance-based level-control approach and the DPDT outputs.
