This unit provides 16 input points, allowing for efficient monitoring of AC-powered sensors, limit switches, or auxiliary contacts. It features a standard 16-point per common configuration and utilizes a \u003cstrong\u003eremovable terminal block\u003c\/strong\u003e for simplified field wiring and rapid module replacement. The module occupies 1 word in the PLC process image and is optimized for low power consumption, requiring only 0.09 A from the 5 VDC backplane supply.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e16 AC digital input points\u003c\/strong\u003e for robust field signal acquisition\u003c\/li\u003e\n\u003cli\u003e100 to 120 VAC input voltage range\u003c\/li\u003e\n\u003cli\u003eStandardized 16-point per common configuration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRemovable terminal block\u003c\/strong\u003e for efficient maintenance and installation\u003c\/li\u003e\n\u003cli\u003eCompact design allocating only 1 word of PLC memory\u003c\/li\u003e\n\u003cli\u003eLow power consumption (0.09 A at 5 VDC)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMonitoring AC power status and line voltages\u003c\/li\u003e\n\u003cli\u003eInterface for AC-powered sensors and proximity switches\u003c\/li\u003e\n\u003cli\u003eGeneral-purpose digital signal acquisition in AC-based control environments\u003c\/li\u003e\n\u003cli\u003eIndustrial machinery and process control systems utilizing 110 VAC control logic\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eFeature\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eOmron\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eCJ1W-IA111\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDevice Type\u003c\/td\u003e\n\u003ctd\u003eAC Input Unit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eI\/O Points\u003c\/td\u003e\n\u003ctd\u003e16 inputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003e100 to 120 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Current\u003c\/td\u003e\n\u003ctd\u003e7 mA (at 100 V, 50 Hz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommons\u003c\/td\u003e\n\u003ctd\u003e16 points, 1 common\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExternal Connection\u003c\/td\u003e\n\u003ctd\u003eRemovable Terminal Block\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAllocated Words\u003c\/td\u003e\n\u003ctd\u003e1 word\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent Consumption\u003c\/td\u003e\n\u003ctd\u003e0.09 A (at 5 VDC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Weight\u003c\/td\u003e\n\u003ctd\u003e2 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Secure the \u003cstrong\u003eCJ1W-IA111\u003c\/strong\u003e to the CJ-series backplane.
