Each input presents a 9.68 kOhm impedance and the module applies a hardware input filter of up to 150 ms, which debounces the signal before the safety logic sees it — this prevents nuisance trips from contact bounce on mechanical safety switches. The maximum voltage drop across a conducting input is under 2 V DC, so the module leaves enough headroom for the field wiring voltage to still register as a valid ON state at the backplane. ## DIN Rail Fit and Temperature Derating The module occupies a 25 mm wide DIN-rail footprint with a depth of 75 mm and height of 99 mm — a single-slot slice that leaves room for adjacent I/O or bus couplers in a crowded panel. Ambient operating temperature depends on mounting orientation: 0 to 55 °C when mounted horizontally, derated to 0 to 50 °C for vertical installation — the vertical position traps heat against the module body, so the spec accounts for the reduced convection. Rated for 15 gn shock at 11 ms duration, the module survives the mechanical stress of shipping and panel vibration common in industrial enclosures. ## Active Production and Sourcing CE marked for the European market, the module carries the compliance documentation needed for machine builders shipping into CE-regulated jurisdictions.","metaTitle":"Schneider TM5SDI20DFS Safety DC Digital Input Module","metaDescription":"Schneider Electric TM5SDI20DFS safety DC digital input module, 20 sink inputs, 150 ms filtering, 75 mm depth.
