Operating at a nominal input voltage of 24 VDC, it reliably captures and processes binary status signals from field devices, switches, and sensors. This module delivers robust performance, secure data acquisition, and reliable signal integration for complex control architectures.\u003c\/p\u003e\n\u003ch3\u003eSignal Configuration and Input Characteristics\u003c\/h3\u003e\n\u003cp\u003eThe module handles up to 32 discrete input points, structured into dual groups with 16 points per common terminal to support flexible field wiring arrangements. Designed for standard 24 VDC logic environments, each channel operates efficiently with a nominal input current of 5.5 mA, ensuring clear distinction of field states while maintaining low thermal output.\u003c\/p\u003e\n\u003ch3\u003eElectrical Isolation and Power Performance\u003c\/h3\u003e\n\u003cp\u003eTo protect control electronics from transient voltage spikes and ground loops, the circuitry supports high-voltage isolation rated up to 1500 VDC for 1 second. Total power dissipation is maintained at a maximum of 6.1 W, providing an energy-efficient profile for high-density cabinet installations while ensuring steady operational stability.\u003c\/p\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\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eHoneywell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eTC-IDD321\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eDigital Input Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Points\u003c\/td\u003e\n\u003ctd\u003e32 PT (16 points per common)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Input Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Current\u003c\/td\u003e\n\u003ctd\u003e5.5 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Dissipation\u003c\/td\u003e\n\u003ctd\u003e6.1 W max\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation Voltage\u003c\/td\u003e\n\u003ctd\u003e1500 VDC for 1 s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Weight\u003c\/td\u003e\n\u003ctd\u003e0.55 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: How are the input channels organized on the TC-IDD321 module?A: The 32 digital input channels are arranged into two distinct groups, providing 16 points per common terminal for organized field wiring.\u003c\/p\u003e\n\u003cp\u003eQ: What is the nominal operating voltage and current for the input channels?A: The channels operate at a nominal voltage of 24 VDC with a nominal input current of 5.5 mA per point.\u003c\/p\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":49395364233496,"sku":"TC-IDD321","price":238.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/3483\/3688\/files\/TC-IDD321_2.jpg?v=1732673630","url":"https:\/\/www.innoplcsync.com\/products\/honeywell-tc-idd321-digital-input-module","provider":"InnoPLC Sync Co., Ltd.","version":"1.0","type":"link"}
