Electrical connection to each other of two valves - 6890 GC

Discussions about GC and other "gas phase" separation techniques.

Dear all,

I have to connect electrically to each other 2 (or 3) valves and control them simultaneously through a 6890 GC. My question is: how can I control simultaneously more than one valve, taking into account that the control has to be through the GC (P-22 section in the main circuit board pinout)?

I am not experienced in electrical connections...

Thank you for your help.
If you have no experience in electrical connections, you should not attempt this upgrade your self. One false connection and you could end up destroying the main board.

It is still possible to buy upgrade kits from Agilent to add valves to a 6890. You will then get the correct components for your GC.
