Caution when working on 230V AC power, it is extremely dangerous!

To upgrade an 8 channel relay to a 4-channel Shutter Actuator  requires only a small change.
It is here used per engine, a changer and a jailer.
First, the circuit diagram:


Here is the draw for use as a Venetian blind. Will you have to switch rather than just loads
the change-over NC/NO relay to only NO Relays !

Here I'm able  to easily mounting because I  print a silkscreen with toner transfer method.  

There are the green terminals are used, the slightly better fit and also from
Big C used.

After mounting the board would look all right well ....

Since it 70mm DIN rail housing the housing for a few more cents at Big C is also available with transparent lid,
I got time this made for a change.
The LED should look triangular. To this end I have in a 5mm strong 5.2 mm aluminum sheet one hole
drilled. Into it put the LED rear fixed with a fingernail and on a belt sander
plan ahead sanded. To make the LED's triangular look to the rest of the area I have
painted black with a Marker. A small remnant of platinum pointed sawn served as a template.

The label is missing yet, here I'll take a sticker and label with a punch, the
Punch holes for the LED's.

Here you can see is 2 copies.
