All 16 points are DC 24V digital inputs — there are no outputs whatsoever. The \"EX\" in the part number tells you this directly: \u003cstrong\u003eE = Extension module, X = Input (X addresses in Mitsubishi FX notation)\u003c\/strong\u003e. If you're looking for output expansion, that's the FX2N-16EYR (relay) or FX2N-16EYT (transistor).

For NPN sensors: connect S\/S to 0V (COM) — sensor output connects to the input terminal and pulls it low to activate. For PNP sensors: connect S\/S to 24V DC — sensor output connects to the input terminal and pulls it high to activate. The hardware is the same either way; it's purely a wiring configuration difference. Refer to the FX2N Hardware Manual for the precise terminal diagram, and note that you cannot mix NPN and PNP sensors on the same module — the S\/S setting applies to all 16 inputs simultaneously.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eQ4: How do I find out which X addresses this module will be assigned in my system?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe addresses are assigned automatically in sequence from left to right across the extension bus, starting from the next available X address after the base unit's last native input. To determine the starting address: count the native input points on your base unit (e.g., FX2N-32MR has 16 inputs → X0–X17 in octal), then count any input extension modules already connected to the right. The first FX2N-16EX added after an FX2N-32MR takes X20–X37; a second takes X40–X57; and so on. Remember that FX address numbering is \u003cstrong\u003eoctal\u003c\/strong\u003e — X7 is followed by X10, not X8. Output modules on the bus do not affect input address counting.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eQ5: Does adding this module require any changes to the GX Works2 program or hardware configuration?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eNo parameter changes or hardware configuration downloads are needed for the FX2N-16EX-ES\/UL. The FX2N and FX3U CPUs scan the extension bus automatically at power-up and recognize connected modules. The new X input addresses become immediately available in the PLC program without any software configuration. You do need to update your \u003cstrong\u003eladder program\u003c\/strong\u003e to add the contact logic referencing the new X addresses — but the module itself needs nothing configured. This is in contrast to special function modules (like the FX2N-4AD-PT), which require explicit FROM\/TO instructions in the program to access their buffer memory.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eQ6: What is the input response time, and can it be changed?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe default input response time is \u003cstrong\u003e10ms\u003c\/strong\u003e — this is a digital filter built into the input circuit that prevents false triggering from contact bounce and electrical noise. For most general-purpose inputs (pushbuttons, limit switches, proximity sensors at normal machine speeds), 10ms is perfectly adequate. On FX3U systems, the input filter time for the first 8 inputs (X0–X7) can be adjusted in the PLC parameters down to 0ms (unfiltered) or up to 60ms, useful when those inputs are used for high-speed counting or when additional filtering is needed in noisy environments. On FX2N systems, the filter time is fixed at 10ms and cannot be adjusted via parameters. Note that the adjustable filter only applies to the base unit's built-in high-speed inputs — the extension module inputs on FX2N are fixed at 10ms regardless.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eQ7: How many FX2N-16EX-ES\/UL modules can I connect to a single FX2N system?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe FX2N supports a maximum of \u003cstrong\u003e256 I\/O points\u003c\/strong\u003e total across the base unit and all extension modules combined, and a maximum of \u003cstrong\u003e8 extension modules\u003c\/strong\u003e on the right-side bus (input and output modules counted together). In practice, a fully loaded system with an FX2N-32MR (16 in + 16 out) and eight FX2N-16EX modules would have 16 + 128 = 144 input points and 16 output points — well within the 256-point limit. Before adding modules, also verify the extension bus \u003cstrong\u003epower budget\u003c\/strong\u003e: each FX2N-16EX-ES\/UL draws approximately 50mA from the 5VDC extension bus, and the FX2N base unit has a maximum extension bus current capacity (typically 460mA for standard CPUs). Exceeding this causes intermittent module communication errors that can be difficult to diagnose.\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-16EX-ESUL_4_800x800_d55deac0-5a52-4002-9643-ee305e4725b6.jpg?v=1772774803\" alt=\"\"\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"topsdevice","offers":[{"title":"Default Title","offer_id":42782144167997,"sku":null,"price":71.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0635\/6516\/8701\/files\/MitsubishiFX2N-16EX-ES_UL.jpg?v=1773720784","url":"https:\/\/topsdevice.com\/products\/fx2n-16ex-es-ul-genuine-mitsubishi-fx2n16eyresul-plc-module","provider":"topsdevice","version":"1.0","type":"link"}
