and provides eight differential analog inputs with selectable voltage or current modes. Its conversion is handled through a successive-approximation method with a switched-capacitor front end, ensuring quick response and stable data output. The module is compatible with fixed and modular SLC 500 systems and can be installed in any chassis slot except slot 0. Featuring multiple digital filter settings, a wide bandwidth range, and continuous autocalibration, it is built to maintain measurement accuracy in noise-prone industrial environments.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eEight Differential Channels: Provides 8 non-isolated differential analog inputs for flexible multi-signal applications.\u003c\/li\u003e\n\u003cli\u003eSelectable Input Modes: Supports a full range of voltage (0–10V, 1–5V, 0–5V, ±10V) and current (0–20 mA, 4–20 mA, ±20 mA, 0–1 mA) signal types.\u003c\/li\u003e\n\u003cli\u003eFast Conversion Technology: Uses successive approximation A\/D conversion for quick response in demanding control processes.\u003c\/li\u003e\n\u003cli\u003eProgrammable Filters: Offers multiple low-pass filter frequencies from 1 Hz to 75 Hz to optimize noise reduction.\u003c\/li\u003e\n\u003cli\u003eBackplane Powered: Draws both 5V and 24V power directly from the SLC chassis without external supply requirements.\u003c\/li\u003e\n\u003cli\u003eWide Compatibility: Works with SLC 5\/01 through SLC 5\/05 processors in Class 1 or Class 3 modes (depending on controller).\u003c\/li\u003e\n\u003cli\u003eDiagnostic LEDs: Includes individual channel status indicators plus a module status LED for simplified troubleshooting.\u003c\/li\u003e\n\u003cli\u003eRemovable Terminal Block: Enables fast module replacement without rewiring, ideal for maintenance and system upgrades.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe 1746-NI8 provides the performance and adaptability needed for precise analog measurement in a broad range of SLC 500 automation applications.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":47061492859178,"sku":"1746-NI8","price":289.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/0392\/4266\/files\/1746-NI8.jpg?v=1722256773","url":"https:\/\/iqelectro.com\/products\/allen-bradley-1746-ni8-slc-500-8-channel-16-bit-analog-input-module","provider":"IQElectro","version":"1.0","type":"link"}
