How to connect VM140 and VM129

Hello,
Sorry for that, the documentation looks not so clear enough for me and to avoid any mismatch, would you be so kind and confirm how to ?
The VM140 has a DC 12v and both VM129 have 12V AC.

question 1 :
I would like to command the 8 relay of the VM 129 with the 8 VM140 analog output.
On my left a VM 140 output with
analog output set one : GND PWM DA1 DA2 DA3 DA4
analog output set two : GND GND DA5 DA6 DA7 DA8
on my right a VM 129 input with 20 screws ( too mutch for me :slight_smile: )
with RS232 O IN Vout 0 +12v 0 1 0 2 0 3 0 4 0 6 0 7 0 8
how to connect both cards ?

question 2 :
I would like to command the 8 relay of the VM129 with the 8 VM140 digital output.
On my left a VM 140 output with
digital output set one : CLAMP 08 07 06 05 GND
digital output set two : CLAMP 04 03 02 01 GND
on my right a VM 129 input with 20 screws ( still too mutch for me :slight_smile: )
with RS232 O IN Vout 0 +12v 0 1 0 2 0 3 0 4 0 6 0 7 0 8
and again, how to connect both cards ?

many thanks and have a nice day.

You can not use the analog outputs of the VM140 to drive the VM129.

You can connect the digital outputs O1…O8 of the VM140 to the VM129 inputs similar way as described in the manual on p. 7. : velleman.eu/downloads/0/modu … _vm129.pdf
The example drawing is for the VM110 but it is applicable to VM140 too.
