I need to control pH range between 0 to 14. How can I control an acid pump and caustic pump to control pH in the logo? How can you control two outputs with the PI instruction? I would also need a deadband between the ranges of the pumps so they never run at the same time. Any help would be appreciated. Thank you, Adam ------------------------------------------------------------------------------------------ |

I have a Logo8. The analog signal coming in is 4-20ma and the 2 analog outputs are 4-20ma. Best Regards, Adam |
