Omron Analog Input

Hi,

I have CQM1-AD042 analog input module, using two inputs that are attached to Dwyer pressure modules with an output of 4-20ma with a pressure range of 0-30 psi.

I need to know how to read the pressure values, the Dwyer modules are hooked up to the analog module channels #1 & #2 as current.

Anyone of any example logic or a place to find this?

Thanks,

I would normally not even bother scaling the value but just use the raw value - compare input word to desired value - turn on a bit to drive a timer (or timers) - determine yes/no for 2 seconds.
