The R612B provides more than double the slot capacity—12 vs. 5—so a panel specified for the R65B would require significant rewiring to accommodate the larger footprint and different module layout. These are not drop-in interchangeable; the slot count alone dictates a different backplane layout.","metaTitle":"Mitsubishi R612B Extension Base Unit, 12 Slots","metaDescription":"Mitsubishi MELSEC iQ-R series extension base unit with 12 slots, one power supply slot.
