Designed to interface with field devices such as sensors, limit switches, and pushbuttons, this module ensures reliable signal acquisition for industrial control systems. With its robust 10-30V DC operating range and efficient backplane current consumption, it serves as an essential component for modular automation environments requiring precise digital feedback.\u003c\/p\u003e\n\n\u003ch3\u003eCore Technical Advantages\u003c\/h3\u003e\n\u003cp\u003eThis module features a sourcing wiring configuration, making it compatible with NPN (current-sinking) field devices. It delivers exceptional performance with a maximum signal delay of only 8ms, ensuring rapid response times for time-critical logic. The hardware is optimized for efficiency, drawing just 85mA from the 5V DC backplane, which allows for higher module density within a single chassis without overloading the power supply. Its high-off-state voltage tolerance and low off-state current leakage provide superior noise immunity in electrically active industrial settings.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 20px 0; font-size: inherit;\"\u003e\n  \u003cthead\u003e\n    \u003ctr style=\"background-color: #f8f8f8;\"\u003e\n      \u003cth style=\"border: 1px solid #dddddd; padding: 12px; text-align: left;\"\u003eFeature\u003c\/th\u003e\n      \u003cth style=\"border: 1px solid #dddddd; padding: 12px; text-align: left;\"\u003eSpecification\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 12px;\"\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 12px;\"\u003eAllen-Bradley\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 12px;\"\u003e\u003cstrong\u003eCatalog Number\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 12px;\"\u003e\u003cspan style=\"color: #003399;\"\u003e\u003cstrong\u003e1746-IV16\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 12px;\"\u003e\u003cstrong\u003eNumber of Inputs\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 12px;\"\u003e16 Channels (Sourcing)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 12px;\"\u003e\u003cstrong\u003eVoltage Range\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 12px;\"\u003e10–30V DC (24V DC Nominal)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 12px;\"\u003e\u003cstrong\u003eProduct Weight\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 12px;\"\u003eApprox. 0.28 kg (0.62 lbs)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 12px;\"\u003e\u003cstrong\u003eBackplane Current\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 12px;\"\u003e85 mA @ 5V DC\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eInstallation \u0026amp; Engineering Guide\u003c\/h3\u003e\n\u003cp\u003eTo install the module, insert it into any available slot in an SLC 500 chassis except slot 0 (reserved for the processor). Ensure that the sourcing wiring configuration is strictly followed, connecting the negative side of the field device to the module input. Utilize high-quality 14 or 16 AWG wiring to maintain signal integrity over long cable runs. For troubleshooting, refer to the front-panel LED indicators, which provide real-time status updates for each of the 16 input channels, facilitating rapid diagnostic checks during commissioning or maintenance.\u003c\/p\u003e\n\n\u003ch3\u003eEngineering Advantages\u003c\/h3\u003e\n\u003cp\u003eThis Allen-Bradley input solution excels in applications where cabinet space and power efficiency are critical.
