Note:
1. The relay in the 61F-GP-NH 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.
2. 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.
3. 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.
4. Possible to use with 10 kΩ or less, however, this may cause reset failure.
Caution: In the interenst of product improvement, specifications are subject to change without notice.
