4 DC inputs on the FX2N-8ER expect a sink (NPN) signal at 24 VDC, with 4.3 kΩ impedance drawing 5 mA per point. Relay outputs handle 2 A resistive per point, 8 A per four-point common. Response time is about 10 ms ON-to-OFF. Powered from the PLC backplane; no external supply needed.
Integration
Mounts on DIN rail; vertical M3 screw terminals accept solid or ferruled wire. Ambient operating temperature 0 to 55 °C, storage -25 to 75 °C. Rated vibration per IEC 61131-2: 0.075 mm amplitude at 10-57 Hz, 9.8 m/s² at 57-150 Hz. Use altitude limited to 2000 m or less.
