HRH-8/24V

• Relay is designed to control the level of conductive liquids in wells, tanks, pools, tankers, reservoirs,... (replacement HRH-1).
• Galvanically isolated supply and guard circuits.
• Within one device, the following confi gurations can be selected: - 2x one-level monitoring (in separate tanks) - 1x two-level monitoring (in one tank) - pumping from one tank to another.
• DIP switch selection on the front panel (8 functions).
• Adjustable probe sensitivity (for each probe separately).
• Adjustable relay switching delay (for each probe separately).
• 10 Hz watch frequency prevents polarization of the liquid and increases resistance to interference by network frequency.
