I am currently controlling turnout solenoids (Peco) on dc with toggle switches on my layout. The common feed for each solenoid is connected locally to a common return wire and two longer wires feed back to the switch on a control panel.

I would like to change to dcc operation using YD8008 units. Is it possible to connect the common feeds on the YD8008 to a common return system or would I have to rewire each solenoid with 3 wires to the decoder?
I have over 30 turnouts to control so I would be using 3 x YD8008.

Thank you.

Hi,

?

All returns for 1 (!!) YD8008 may be connected in Common. ( as they are internally )

?

Reason for this is, that the "Commons" are supplied by the internal CDU. Connecting the "Commons" of multiple YD8008's will definitively destroy one or more of them.

I have over 30 turnouts to control so I would be using 3 x YD8008.

Then you would need 4. Since each 8008 handles 8 Turnouts. ( 3x8 = 24 )

Greets,
