The GT15-QBUS2 is a bus connection unit for the Mitsubishi MELSEC-Q series, used to extend the I/O bus to remote or adjacent racks. It occupies 16 I/O points and draws 0.44 A from the 5 V backplane supply.
Integration notes
The 16-point I/O assignment supports both intelligent and standard modules. Verify the backplane current budget — the 0.44 A draw at 5 VDC is within typical MELSEC-Q power supply capacity but should be summed across all bus units on the same rail.
