This makes the module suitable for installations in humid or dirty environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCan I use this module with both current and voltage sensors on different channels?\u003c\/strong\u003e Yes, you can configure each channel independently for any of the five voltage or three current ranges. This lets you mix transmitter types on a single \u003cstrong\u003e1771-IFEK\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHow does the 1771-WG wiring arm simplify maintenance?\u003c\/strong\u003e The wiring arm connects all field wires and remains in the chassis when you remove the module. You can replace the electronic module without disconnecting any wiring, saving time and reducing wiring errors.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat do the front‑panel LEDs indicate?\u003c\/strong\u003e A steady green RUN light means the module is communicating with the PLC5. A red FAULT light signals a configuration error, loss of communication, or a hardware problem.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIs an external power supply required for the \u003cstrong\u003e1771-IFEK\u003c\/strong\u003e?\u003c\/strong\u003e No, it draws all necessary power (750 mA at 5V) from the backplane of the 1771 I\/O chassis.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat is your typical shipping time for this module?\u003c\/strong\u003e We keep the \u003cstrong\u003e1771-IFEK\u003c\/strong\u003e in stock as new original surplus.
