The Mitsubishi Electric QD77MS2 is a Simple Motion Module that lives in the PLC I/O & Expansion Modules category — it's the motion control brain for a Mitsubishi PLC rack, handling coordinated axis moves without tying up the main CPU cycle.
Power budget and physical footprint
Internal current consumption is 0.6 A at DC 5 V — that's the load the rack power supply sees from this slot alone, so add it into your backplane budget before you fill the remaining slots.
