Hi, Here is my problem. I must command a proportional hydraulic valve which use a 0 +-10V signal. From 0 to +10v, it command the B solenoid and from 0 to -10v it command the A solenoid. Now, I have a F2-02DAS-2 analog 16bit volt output card but cannot figure how to make them work together. I mean to use 1 channel to command my valve. I was thinking to use a signal converter to convert 0...+10v signal to -10...+10v but I don't trust this concept. I would have to give a 5v signal to put the valve to off, it is not very safe. The valve doesn't have an enable feature also. Someone have some suggestion? Thanks! Phil
