Base unit combination
The following tables show which base unit combinations are possible.
: Combination possible, : Combination not possible
*1 If the combination contains base units other than the extended temperature range base unit, use in an operating ambient temperature of
0 to 55.
*2 Only the MELSEC-Q series extension base unit can be connected to the lower level of an RQ extension base unit. ( Page 113
When MELSEC-Q series modules are used)
Only use the redundant power supply base unit for redundant configuration of power supply modules in the
entire system. If another type of base unit is used together and an error occurs in its power supply, the entire
system stops.
