Kaiser Nienhaus 336400 Limit switch

The exceeding of the adjusted sensitivity is immediately displayed by the LED. At the same time the relay contact is activated. Depending on the setting, the relay remains active only for either 2 seconds or it will be permanently switched during the rainy period. The fixed delay time of 30s also provides at shortfalls in the short circuit threshold a continuous stable operation condition.
