Bus interface and slot cost
The Mitsubishi Electric GT15-75QBUSL is a bus connection unit that bridges a GOT1000-series HMI terminal to a QCPU (Q Mode) programmable controller through the Q-bus, occupying 16 intelligent I/O points on the rack and drawing 0.44 A from the 5 VDC backplane. That fixed slot cost is the spec that actually drives panel layout — the unit sits on the base rack like an intelligent module and is sized into the I/O assignment map at commissioning, not retrofitted later. One connector IN and zero connector OUT confirms the unit is a single-segment terminator on the Q-bus rather than a repeater or branch — the cable enters from the GOT and lands on the backplane, with no onward trunk to a downstream node.
Lifecycle posture and BOM fit
Lead time on this line typically falls in the 1–10 working day range, which matters for MRO replenishment more than for greenfield builds: a spare kept against a hot panel can be replenished on that window without taking the line down for a wait.
