Greg_E Posts: 88 Rating: (2)	Hi to all, have some questions about S7-224XP. I know there are 2 analogue inputs and 2 analogue outputs, the inputs are voltage if ill put there 250 ohm resistor can i connect an current transmitter to it? and to put 250 ohm resistor to the voltage output will i get 4-20mA? the second output ok its current. or i mistaken here with the analogue output and there is only one that i can wire as current or/and voltage? Thanks in advance, Best Regards, Greg.
