This module functions as an electrical interface that monitors alternating current discrete signals from field devices such as limit switches, pushbuttons, and auxiliary contacts, converting them into digital state logic for the process controller. It features 16 individually isolated channels designed for a nominal input of 120 VAC, complying with IEC Type 1+ input compatibility specifications. Galvanic isolation barriers are engineered between individual channels and from user-to-system lines to eliminate ground loop interference and shield the supervisory control backplane from high-voltage field spikes.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e16 individually isolated input circuits providing distinct channel-to-channel galvanic separation.\u003c\/li\u003e\n\u003cli\u003eIEC Type 1+ input compatibility parameters for stable industrial signal sensing.\u003c\/li\u003e\n\u003cli\u003eProgrammable input filter delay times allowing tailored debounce tuning.\u003c\/li\u003e\n\u003cli\u003eStandard physical form factor optimized for standard C200 controller chassis slots.\u003c\/li\u003e\n\u003cli\u003eHigh transient voltage protection verified through strict factory isolation testing.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMonitoring of discrete machinery states and safety interlocking switches.\u003c\/li\u003e\n\u003cli\u003eInterface management for 120 VAC field control circuits and pushbuttons.\u003c\/li\u003e\n\u003cli\u003eDistributed Control Systems (DCS) sequential control logic tracking.\u003c\/li\u003e\n\u003cli\u003eSubsystem signaling inside chemical processing, refining, and utility generation facilities.\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\u003eParameter\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\u003eHoneywell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eTK-IDK161\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eAC Input Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Series\u003c\/td\u003e\n\u003ctd\u003eC200 \/ Experion System Chassis I\/O (CIOM-A)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Points\u003c\/td\u003e\n\u003ctd\u003e16 (individually isolated)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Input Voltage\u003c\/td\u003e\n\u003ctd\u003e120 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOn-State Voltage Range\u003c\/td\u003e\n\u003ctd\u003e79-132 VAC, 47-63 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Compatibility\u003c\/td\u003e\n\u003ctd\u003eIEC Type 1+\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShort\/Inrush Current\u003c\/td\u003e\n\u003ctd\u003e250 mA peak (decaying to \u0026lt;37% in 22 ms, without activation)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOff-State Voltage (Maximum)\u003c\/td\u003e\n\u003ctd\u003e20 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOn-State Current (Minimum)\u003c\/td\u003e\n\u003ctd\u003e5 mA @ 79 V, 47-63 Hz;
