It captures digital signals from field devices such as sensors, limit switches, and pushbuttons to provide fast, reliable input detection for industrial control applications.\u003c\/p\u003e\n\u003ch3\u003eInput Channel Structure and Logic Options\u003c\/h3\u003e\n\u003cp\u003eThe module features 16 discrete input channels operating at a nominal 24 VDC within a voltage range of 20.4 to 28.8 VDC. The inputs support both sink and source wiring configurations, providing flexibility when integrating various field device contact types. All 16 channels share a single common point, and each channel draws 7 mA at standard operating voltage with an input impedance of 3.4 kΩ.\u003c\/p\u003e\n\u003ch3\u003eSignal Timing and System Isolation\u003c\/h3\u003e\n\u003cp\u003eTo filter contact bounce and ensure stable signal detection, the \u003cstrong\u003eTM2DDI16DT\u003c\/strong\u003e features a 4 ms response time for both 0-to-1 and 1-to-0 transitions. While individual channels share a common circuit without channel-to-channel isolation, the module provides 500 V galvanic isolation between field input channels and internal controller logic for 1 minute to protect backplane communication circuits.\u003c\/p\u003e\n\u003ch3\u003ePhysical Design and Installation\u003c\/h3\u003e\n\u003cp\u003eThe compact module measures 23.5 mm in width, 90 mm in height, and 84.6 mm in depth, with a net weight of 0.065 kg. It mounts on a standard 35 mm symmetrical DIN rail and connects to field wiring using a single removable screw terminal block. Front-panel status indicators on the display block provide real-time channel diagnostic visibility.\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\u003eModel\u003c\/td\u003e\n\u003ctd\u003eTM2DDI16DT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSchneider Electric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eDiscrete Input Expansion Modules\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Systems\u003c\/td\u003e\n\u003ctd\u003eModicon M238, Twido, Advantys OTB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiscrete Input Number\u003c\/td\u003e\n\u003ctd\u003e16\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiscrete Input Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC (20.4...28.8 VDC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiscrete Input Logic\u003c\/td\u003e\n\u003ctd\u003eSink or source\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiscrete Input Current\u003c\/td\u003e\n\u003ctd\u003e7 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Impedance\u003c\/td\u003e\n\u003ctd\u003e3.4 kΩ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Common Points\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResponse Time\u003c\/td\u003e\n\u003ctd\u003e4 ms (OFF to ON \/ ON to OFF)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation\u003c\/td\u003e\n\u003ctd\u003e500 V for 1 min (channels to internal logic)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInternal Current Consumption\u003c\/td\u003e\n\u003ctd\u003e40 mA at 5 VDC (state 1, all inputs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eElectrical Connection\u003c\/td\u003e\n\u003ctd\u003e1 removable screw terminal block\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Support\u003c\/td\u003e\n\u003ctd\u003e35 mm symmetrical DIN rail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (W x H x D)\u003c\/td\u003e\n\u003ctd\u003e23.5 mm x 90 mm x 84.6 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNet Weight\u003c\/td\u003e\n\u003ctd\u003e0.065 kg\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: Can the \u003cstrong\u003eTM2DDI16DT\u003c\/strong\u003e module be used with controllers other than the Modicon M238?
