This is the backbone of a medium-density Q-series rack; the 8-slot count gives you room for a mix of digital, analog, and special-function modules before you need an extension base. The mature label doesn't signal an imminent end, but if you're freezing a BOM for a multi-year run, it's worth locking in a forward purchase quantity now. Mounting is standard DIN rail or direct screw; the power supply slot is on the left end of the rack, which is the typical Q-series layout. Verify that your CPU model is compatible with the 8-slot backplane before wiring.","metaTitle":"Q38B PLC Rack 8 Slots, 1 Power Supply Slot, Main Base Unit","metaDescription":"Q38B PLC rack base unit with 8 slots and 1 power supply slot.
