1) i just notice the analog output from the 15 pins are 0-20mA or 0-10V, if not mistaken most of the analog input module nowadays are 4-20mA, 0 to 5 V DC, 1 to 5 V DC or -10 to 10 V.
2) Based on the wiring diagram can we tell if the analog module on the right hand side are actually AI or AO? And it's operating range?
