Hi, I have a application that will control 4 air bags in a car by 4 air valves with 8 solenoids that will increase or decrease the air pressure. Too that I have 4 analog 0-5v transmitters to my 0BA7. In my program a can set a value that the air bags will achieve and so far everything works fine, but! I belive the pressure and the analog value increases too fast so it will pass the set value and after that it has to increase some psi too reach the setpoint again. so my problem is that the relay outputs pulsing + and - for a while to be exact and it doesn´t sounds nice in the relays or my solenoids. Have you guys any idea how a can "ramp" down the speed the last 5psi or something like that to make the system live longer.
