Note:Note:

Note:The relay in the 61F-G1H/-G2H/-IPH de-energizes when there is water present across the Electrodes, whereas the relay in the 61F-GP-N8HY energizes when there is water present across the Electrodes.

Note:Models are available for 2 km and 4 km.

Note:The length when using completely-insulated, 600-V, 3-conductor (0.75 mm2) cabtire cables. Usable cable lengths will become shorter as the cable diameter or number of conductors becomes larger.

Note:The insulation resistance and dielectric strength indicate values between power terminals and Electrode terminals, between power terminals and contact terminals, and between Electrode terminals and contact terminals.

Note:Possible to use with 15 kΩ or less, however, this may cause reset failure.

Note:High-sensitivity Controllers use advanced operation.
When the power supply voltage is applied, if there are some liquids between the electrodes (ground and operation electrodes), the internal relay will not operate.
When the power supply voltage is applied, if there are no liquids between the electrodes (ground and operation electrodes), the internal relay will operate.
