It's a straight-up I/O slice — no CPU, no power supply of its own, just eight channels of 24 VDC sink inputs with a 4.3 kΩ impedance and a nominal 5 mA draw per point at 24 VDC. The input ON threshold is 3.5 mA; OFF is 1.5 mA or less, with a response time around 10 ms. Isolation is via photocoupler, and the terminal block is vertical M3 screws. The FX2N-8EX connects to FX1N, FX3G, FX2N, FX3U, FX1NC, FX3GC, FX2NC, and FX3UC sequencers. For FX1NC and FX2NC, an adapter is required; for FX3GC and FX3UC, either that adapter or an FX3UC-1PS-5V. The 4.3 kΩ impedance and 5 mA at 24 VDC are typical for Mitsubishi's FX-series sink inputs — they'll work with most standard 3-wire NPN sensors and dry contacts. The 10 ms response is fine for general-purpose monitoring (pushbuttons, limit switches, relay contacts) but too slow for high-speed counting or encoder feedback. The vibration specs (0.075 mm amplitude at 10–57 Hz, 9.8 m/s² at 57–150 Hz) are standard industrial; it'll hold up in a cabinet on a machine base, but don't mount it directly on a vibrating motor.","metaTitle":"Mitsubishi FX2N-8EX FX Series 8-Point Sink Input Extension B","metaDescription":"FX2N-8EX is end-of-life (EOL). 8-point sink input block for FX1N, FX2N, FX3U, FX3G series PLCs.
