It seems that the Hella delayed relay 5HE 996 152-151 is suitable for application as beeper/led adjustable delay on low level alarm.

Hella Italy priced it 72€ + VAT they are crazy.

English people refers to approx 30£.

Can some-one search for this relay and pricing, thanks.

I type the Nr. from the Relay in Google and here is the result: http://www.teilesuche24.de/hella/zeitre ... e996152151

44,80 € + Shipping Cost for Germany 5,50€ or Shipping Costs for the EU 18,60,- €
