Hi,
I am trying to connect PVM110N-1 to P8056-1 relay board, in order to driver relays from DLL on a windows based PC.
It seems that I can not connect directly 01-08 from PCM110N to I1-I8 from P8056-1 (does not work).
Should I Solder transistors T1-T8 on P8056 to make it work ? Will it work ?
Thanks for your help.

There is no need to solder the transistors on the K8056, it should work without.
Try the K8056 inputs first. If you short each input, the corresponding relay should energize.
Next, you can connect each input of the K8056 to the output of the VM110.
Make sure you connect the K8056 GND to the VM110 GND.
Now it should work.
OK this was a power supply issue. It is working fine now. Thanks for your very prompt support.
