The Mitsubishi LD75D2 is a 2-axis positioning module that drops into a MELSEC PLC rack and drives coordinated motion on automated machinery. It sits in the PLC Expansion Modules class under PLCs and Accessories, so the slot count, base unit, and I/O assignment are the MELSEC family's, not a third-party bus. Lifecycle stage reads current, so the part is specified against normal MELSEC supply rather than the broker channel.
