switching high inductance loads

[Luciano]

Hi,

See attached schematic (JPG file).

Make sure you allow enough time for the relay to switch back
to its unenergized position before you activate the solenoids
with the 2803.

On my schematic D2 and D4 are not necessary if you connect +12V
to the PIN 10 of the IC 2803.

The schematic only shows two solenoids.
Do the same for the other four solenoids.

Please verify before you try the schematic!

I am on vacation for three days.
