  4. FX2N-80MR Wiring Question

    Hey thanx, now another question, if all I want is 24 volts I/O should I power the PLC with 120 VAC using the L and N terminals or should I powered the PLC by connecting 24 volts to the 24 and 0 terminals? also I noticed there are two sets of 24 v and 0 terminals should I jump 24 volts to both sets or just to one set if so which one? Thank you for all your help.
