Precautions *1:SYSMAC C series modules with "-N" at the end of their model name are not listed because only the difference is whether a connector is included or not.
*2:If the existing module uses 24VDC negative common, consider rewiring to the QX81 or QX81-S2.
*3:For replacement, two MELSEC-Q series modules and two conversion adapters are required.
*4:If the existing module uses 24VDC negative common, consider rewiring to the QX82 or QX82-S2.
*5:Since the number of points per common changes (16 points/common → 32 points/common), check the common terminal connection of the module before replacement.
*6:If the existing module uses a different power supply for each 16-point group, consider rewiring to multiple QX40s or multiple QX80s.
If the existing module uses negative common, consider rewiring to the QX81 or QX81-S2.
*7: For replacement, two MELSEC-Q series modules and two conversion adapters are required.
If the existing module uses a different power supply for each 16-point group, consider rewiring to four QX40s or four QX80s.
If the existing module uses negative common, consider rewiring to the QX82 or QX82-S1.
*8: If the existing module uses a different power supply for each 16-point group, consider rewiring to two QY40Ps or two QY70s.
*9: If the existing module uses negative common, consider rewiring to the QX81 or QX81-S2.
