That's one part number covering eight process-variable inputs — temperature, pressure, flow, level — on a 4-20 mA loop. ## Backplane power and slot budget The module draws 640 mA from the 5 VDC backplane rail. In a fully loaded Q Series rack with a QCPU, power supply, and several I/O slices, that draw adds up — check the power module's 5 V capacity before committing the slot. Occupied I/O points on the PLC are 16, even though the module has only 8 physical channels. That's the Q Series addressing convention — each analog channel reserves two points in the I/O map. Plan the addressing accordingly in GX Works. ## Field wiring without a breakout board All field connections land on an 18-screw terminal block fitted to the module face. No separate breakout board, no D-sub cable — just strip, terminate, and torque. The terminal block is captive to the module, so a pulled wire doesn't lose the connector.","metaTitle":"Mitsubishi Q68ADI Q Series A/D Input Module, 8 ch, 16-bit","metaDescription":"Mitsubishi Q68ADI analog input module: 8 channels, 16-bit resolution, 0-20 mA, 18-screw terminal.
