Operating as a Special I\/O Unit, it scales I\/O density by providing 8 analog channels in a compact 31 mm backplane slot width. Digital conversion results are continuously mapped into designated Special I\/O Unit memory areas, enabling deterministic scan updating across all 8 channels. Integrated firmware functions include mean value processing, peak value holding, and broken-wire detection for 1 to 5 V and 4 to 20 mA ranges.\u003c\/p\u003e\n\u003ch3\u003ePackage Contents \u0026amp; Ordering Information\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x Omron CJ1W-AD081-V1 Analog Input Unit\u003c\/li\u003e\n\u003cli\u003e1x 18-Point Detachable Terminal Block Assembly\u003c\/li\u003e\n\u003cli\u003e1x Quick Reference Manual Document\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModule Mounting:\u003c\/strong\u003e Lock the module onto a 35 mm DIN rail within the CJ Series CPU rack or Expansion rack.
