It sits downstream of the CPU on the iQ-F extension bus, addressed as a slice in the project rather than as a stand-alone controller. Catalog class is PLC expansion under the iQ-F family; the module is an I/O slice, not a CPU, not a power supply, and not a motion or positioning card. ## Buyer-side takeaway For a buyer landing on this exact order code with an FX5 line to extend: the part is current, the role is a 4-in / 4-out iQ-F slice, and the right move is to quote it to order against the FX5 BOM rather than chase a non-existent cross-reference. Send the FX5-SF-MU4T5 line in on an RFQ with the host CPU model and the existing I/O map so the slice lands in the correct expansion slot.","metaTitle":"Mitsubishi FX5-SF-MU4T5, iQ-F 4-in/4-out expansion","metaDescription":"Mitsubishi FX5-SF-MU4T5 MELSEC iQ-F 4-input / 4-output expansion module, current production.
