It handles programs up to 40K steps and supports up to 4096 I/O points (X/Y) with a refresh I/O control mode — the standard for this family. The instruction set covers 859 instructions, including ladder, list, SFC (MELSAP3/MELSAP-L), function block, and structured text (ST). This breadth means the same CPU can serve both legacy relay-logic migrations and newer ST-based motion or process blocks without a processor swap. ## I/O budget and power draw for rack sizing Total I/O device points are 8192 (X/Y), with 4096 physical I/O points addressable. That is enough for a medium-to-large machine cell — a multi-station assembly line or a packaging skid with several remote racks — without needing a second CPU for I/O handling. The module draws 0.58 A from the 5 VDC backplane supply (0.6 A with an extended SRAM cassette). In a Q-series rack, this must be summed with the power supply module's rating — typical Q6-series supplies provide 3 A or 6 A at 5 V, so this CPU leaves headroom for a dozen I/O or special-function modules on the same backplane. A built-in SD memory card interface (SD and SDHC) supports data logging, recipe storage, and firmware updates without a dedicated programming tool connected. This is the standard method for field upgrades on Q-series CPUs. Sourced to order against the BOM quantity.","metaTitle":"Mitsubishi Electric Q04UDVCPU CPU Module, 40K Steps","metaDescription":"Mitsubishi Electric Q04UDVCPU CPU module for Q series PLC. 40K step program capacity, 4096 I/O points, SD card slot, 859 instructions.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLCs (Programmable Logic Controllers)"],"specifications":{"title":"Q04UDVCPU","Weight":"20 Kg","Product No.":"Q04UDVCPU","description":"CPU Module","Product type":"CPU Module","Control method":"Stored program cyclic operation","Shipping weight":"22 Kg","lifecycle_stage":"mature","I/O control mode":"Refresh","Program capacity":"40K steps","Estimated Lead Time":"Usually ships in 1 - 10 working days.","Memory card interface":"(SD Memory Card, SDHC Memory Card)","Dimensions (L x W x H)":"11.5cm x 2.74cm x 9.8cm","Number of I/O points [X/Y]":"4096 points","Total number of instructions":"859","5VDC Internal Current Consumption":"0.58A (only CPU module), 0.6A (with an extended SRAM cassette)","Number of I/O device points [X/Y]":"8192 points","Program language (sequence control language)":"Relay symbol language (ladder) Logic symbolic language (list) MELSAP3 (SFC), MELSAP-L Function block Structured text (ST)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1,085.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/a99efdbc63c9ffa43802595ee6514d4c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the program capacity and I/O count of Q04UDVCPU?","answer":"The Q04UDVCPU supports 40K steps of program capacity and addresses up to 4096 physical I/O points (8192 total I/O device points X/Y).
