Conductive level switch with two channels for two independent CL2 probes. It signals the liquid level in a tank by controlling the conductivity between an electrode installed in the tank and a common reference electrode. When the electrodes come into contact with the liquid, there is a current flow that causes the instrument to intervene. The voltage between the electrodes is alternating to prevent electrolysis phenomena in the liquid and electrode corrosion. – Control of two independent points – Single-point control or dual control as a level controller for activating/stopping valves or pumps- Power supply: 24 Vac/dc- Power consumption: 2 VA/ 1.8W max.- 2 SPDT output contacts- Dimensions: 90 (height) x 35 (width) x 60 (depth)- Mounting: DIN 35mm rail
