This is the third-generation FX3U platform, built for the installed base of Mitsubishi PLCs that still run production lines worldwide. Power supply accepts 100-240 VAC, so the same unit works across 120 V and 240 V line voltages without a transformer swap — one BOM line for global panel builds. ## 64K-step memory and resource budget Program memory holds 64,000 steps — enough for medium-complexity sequential logic, motion sequences, and analog handling without cramming into a smaller frame. The 512 timers and 235 counters give the application headroom for multi-stage processes and production counting. Power draw is 35 W, which sets the thermal budget for the enclosure — a 35 W continuous load in a sealed cabinet needs ventilation or derating if ambient exceeds 55 °C. The integrated real-time clock includes 16 high-speed counters rated at 100 kHz, covering encoder feedback or fast pulse-train inputs without an add-on module. ## Discontinued — sourcing for the installed base No official successor order code is published. For a line running on FX3U hardware, the practical replacement path is either the FX5U series (different backplane and software — requires a program port) or holding a spare FX3U-32MT/ES-A in the cabinet. We source this unit through independent distribution channels; quantities are confirmed at RFQ against the BOM line.","metaTitle":"Mitsubishi FX3U-32MT/ES-A PLC CPU, 32 I/O, 64K Steps","metaDescription":"Mitsubishi FX3U-32MT/ES-A main unit with 32 I/O (16 inputs, 16 transistor outputs), 64,000-step memory, 100-240 VAC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLCs (Programmable Logic Controllers)"],"specifications":{"Power":"35 W","Timer":"512","title":"FX3U-32MT/ES-A","Origin":"Mitsubishi - Japan","Counter":"235","Product No":"FX3U-32MT / ES-A","description":"FX3U32MTESA DISCONTINUED BY MANUFACTURER LOGIC MODULE 32 I/O THIRD GENERATION POWER SUPPLY: 100 -240 VAC MEMORY PROGRAM: 64,000 STEPS","Power supply":"100 -240 VAC","Product type":"Main units with 32 I/O","Memory program":"64,000 Steps","Shipping Weight":"2 kg","lifecycle_stage":"mature","Estimated Lead Time":"Usually ships in 1-10 working days..","The CPU with 32 I / O":"16 inputs and 16 outputs transistor (S)","Integrated real-time clock":"16 (100 Khz)."}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$86.40","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/af08d22b1c41555a9c9c073ea2f68f89.pdf","sourceUrl":"https://www.automationcontrolandproject.com/cgi/d05_showmore_2.php?start=0&end=39&cat_idx=plc-programming.html&server=https&id=1&action=showmore&domain_alias=automationcontrolandproject-com&pageHtmlType=category_left"},"ai":{"faq":[{"question":"What is the I/O configuration of the FX3U-32MT/ES-A?","answer":"The unit provides 16 digital inputs and 16 transistor outputs (sink/source type), for a total of 32 I/O points.
