The \u003cstrong\u003eFX2N-16EYR-ES\/UL (this unit) has relay contact outputs\u003c\/strong\u003e, capable of switching both AC (up to 240V) and DC (up to 30V) loads at up to 2A per point. The \u003cstrong\u003eFX2N-16EYT-ESS\/UL has transistor (NPN) outputs\u003c\/strong\u003e, which are DC-only (5–30VDC) but support high-frequency switching and \u003cstrong\u003epulse train output (PTO)\u003c\/strong\u003e for stepper and servo drive control. For any application involving AC-powered devices, or where load types are mixed or undecided, choose the EYR (relay) version. For high-speed DC switching or pulse output, choose EYT.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eQ2: Is the FX2N-16EYR-ES\/UL compatible with FX3U PLCs?\u003c\/strong\u003e Yes — the FX2N-series extension modules are \u003cstrong\u003emechanically and electrically compatible with FX3U base units\u003c\/strong\u003e and can be connected to the right-side extension bus of an FX3U in the same way as FX2N extensions. The FX3U CPU automatically assigns Y output addresses to the FX2N-16EYR in sequence. However, FX2N extension modules connected to an FX3U do not support the FX3U's high-speed features on those points — they operate as standard extension I\/O. For FX3UC and FX2NC, a separate bus conversion adapter is required due to the compact connector format on those units.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eQ3: How are Y output addresses assigned when I add FX2N-16EYR to my system?\u003c\/strong\u003e Address assignment is \u003cstrong\u003eautomatic and sequential\u003c\/strong\u003e — no software configuration is needed. The FX2N base unit scans connected extension modules from left to right and assigns Y addresses immediately following the base unit's last native output point. For example, if your FX2N-32MR base unit has outputs Y0–Y17 (octal notation, 16 points), adding an FX2N-16EYR to the right side will assign outputs Y20–Y37 to the extension module. Note that Mitsubishi FX PLCs use \u003cstrong\u003eoctal numbering\u003c\/strong\u003e for I\/O addresses (Y0–Y7, Y10–Y17, Y20–Y27...) — there is no Y8 or Y9. Account for this when writing PLC programs referencing the extension module outputs.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eQ4: What types of loads can the relay outputs switch directly, and what requires an interposing relay?\u003c\/strong\u003e Each relay output contact on the FX2N-16EYR is rated for \u003cstrong\u003e2A at 240V AC or 30V DC\u003c\/strong\u003e. Loads that can be driven directly include: 24VDC solenoid valves under 2A, 110V\/240V AC small solenoid valves, indicator pilot lamps, and coils of motor starter contactors (which typically draw 50–200mA at the coil). Loads that should NOT be driven directly include: motors above a few watts (always switch via a contactor), loads drawing more than 2A, high-inrush loads without suppression (always add a snubber or flyback diode for inductive DC loads), and any load requiring pulse output or switching faster than approximately 10Hz (use transistor output instead). The 8A per common terminal group rating must also not be exceeded — if 8 outputs in a common group are all on simultaneously and each draws 1A, the 8A common limit is already reached.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eQ5: Does the FX2N-16EYR-ES\/UL need a separate 24VDC power supply?\u003c\/strong\u003e No — the FX2N-16EYR-ES\/UL draws its internal logic power directly from the \u003cstrong\u003eFX2N base unit's extension bus\u003c\/strong\u003e, which provides 5VDC for the module's internal circuitry. However, the \u003cstrong\u003eload circuit\u003c\/strong\u003e (the devices connected to the output terminals) requires its own external power supply appropriate to the load voltage — 24VDC, 110V AC, 240V AC, etc. The module does not supply load power; it only provides the relay contacts that switch the external load power. Verify that adding the extension module does not exceed the base unit's extension bus power budget — the FX2N base unit documentation specifies the maximum total current available for extension modules.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eQ6: How do I verify the FX2N-16EYR-ES\/UL is genuine Mitsubishi Electric and not counterfeit?\u003c\/strong\u003e Genuine Mitsubishi Electric FX2N-16EYR-ES\/UL units have the following identifiers: the Mitsubishi Electric diamond logo is clearly molded and printed on the housing; the catalog number label includes the full part number (FX2N-16EYR-ES\/UL), a serial number, date code, and UL\/CE marking; the housing color matches the standard FX2N gray-blue Mitsubishi palette; terminal screw torque markings are present; and the unit ships in the original Mitsubishi Electric factory box with matching catalog number barcode. Counterfeit FX2N modules often have slightly different housing dimensions, poor label print quality, or missing UL markings on the unit itself (only on the box). For critical OEM and replacement applications, request supplier traceability documentation.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eQ7: Can I hot-swap the FX2N-16EYR-ES\/UL while the PLC system is powered?\u003c\/strong\u003e No — the FX2N extension bus is \u003cstrong\u003enot hot-swap capable\u003c\/strong\u003e. Adding or removing extension modules while the system is powered can damage the bus connector pins on both the module and the base unit, corrupt the CPU's I\/O map, and in some cases cause irreversible damage to the base unit's extension bus interface. Always \u003cstrong\u003epower down the entire FX2N\/FX3U system\u003c\/strong\u003e before adding, removing, or repositioning extension modules. After reconnecting and powering on, verify that the CPU correctly recognizes all extension modules and that no I\/O error codes appear before returning the system to operation.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0635\/6516\/8701\/files\/MitsubishiFX2N-16EYR-ESUL_2_800x800_f942ca36-0ab3-4f2a-9b02-23ab215f4087.jpg?v=1772772704\" alt=\"\"\u003e\u003c\/p\u003e","brand":"topsdevice","offers":[{"title":"Default Title","offer_id":42782153474109,"sku":null,"price":39.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0635\/6516\/8701\/files\/MitsubishiFX2N-16EYR-ES_UL.jpg?v=1773719960","url":"https:\/\/topsdevice.com\/products\/fx2n-16eyr-es-ul-new-fx2n16eyresul-mitsubishi-output-extension-module-dc-24v","provider":"topsdevice","version":"1.0","type":"link"}
