Same 16 inputs, same AC power, same form factor. The difference: output stage. The relay version (MR) handles AC and DC loads indiscriminately, switching up to the contact rating — good for pilot lamps, contactors, and solenoid coils. The transistor version (MT/ESS) switches at higher speed (kHz range) and is source-output only, suited for driving DC solenoid valves or interfacing with other transistor-input modules. If the target load requires fast pulse output or has a large inductive kick, the MT/ESS fits; otherwise the MR's contact isolation is simpler to commission. ## Panel fit and I/O wiring basics 16 inputs at 24 V DC sink/source; 16 relay outputs in groups of two; supply 100 to 240 V AC. ## Sourcing this CPU for a BOM freeze Since the lifecycle is current, the FX5U-32MR/ES is a standard catalog item — no need to chase surplus or negotiate a last-time buy. For a new BOM line, specify the exact order code; there is no functional replacement by an alternative Mitsubishi part number at the same I/O count.","metaTitle":"Mitsubishi FX5U-32MR/ES FX5U CPU, 16 Inputs, 16 Relay Output","metaDescription":"FX5U-32MR/ES PLC CPU with 16-point 24 VDC inputs and 16 relay outputs, 100-240 VAC supply, current production, sourced to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":[],"specifications":{"Input":"16 points, 24 V DC, Sink/source","Output":"16 points, Relay","Weight":"0.65 kg","Product No.":"FX5U-32MR/ES","Manufacturer":"Mitsubishi Electric","Power supply":"100 to 240 V AC 50/60 Hz","Product Type":"FX5U CPU Unit","Shipping Weight":"2 Kg","lifecycle_stage":"current","Estimated Lead Time":"1 - 10 Working Days"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$434.00 – $978.48","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/3f24e217fcd9a7e73255dc90cdfdff9e.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/FX5U-32MR%2FES/alternatives.json"},"ai":{"faq":[{"question":"What are the input specifications on this component?","answer":"16 digital inputs, 24 V DC, sink or source wiring configuration."},{"question":"Will the FX5U-32MR/ES drop into a panel specified for the FX5U-32MT/ESS without rewiring?","answer":"The CPU footprint and power supply connections are identical. However, the output wiring differs: the MR uses relay commons (typically grouped by pairs), while the MT/ESS uses transistor source outputs. If the panel's field wiring expects transistor-level signals, the relay outputs will not interface correctly.
