For simple monitoring applications. LLB-10 is a very compact unit and forms part of the NDC series of DIN products.

In its standard version it is designed for normally open contacts (NO) and is particularly suitable for simple monitoring applications.

In spite of its low price, the LLB-10 is superior to ordinary ”diode type” alarms, since it gives a new alarm for each new fault.

The output relay has an adjustable time delay to avoid unnecessary alarms when, for example, connected to a level sensor.
