It communicates over the TM3 backplane bus and requires no external power supply—electronic powered by the internal bus. The module carries CE marking and is rated for pollution degree 2, making it suitable for industrial control panels within controlled environments. Width of 33.5 mm (1.3 in) mounts on standard top-hat rail (IEC 60715) or panel with fixing kit, fitting dense I/O layouts in a cabinet. Inputs are accessed via a single connector; typical current draw is 34 mA from the 5 V DC backplane plus 5 mA per input when on. ## What the electrical ratings mean for fit Input impedance of 4.4 kΩ gives a nominal 5 mA at 24 V DC, which is standard for TM3 drops. Guaranteed state 1 above 15 V and 2.5 mA; state 0 below 5 V and 1 mA. These thresholds match IEC 61131-2 type 3, offering higher noise immunity than basic type 1—important in panels with contactors or variable-frequency drives nearby. Response time is 4 ms maximum on both turn-on and turn-off, so the module handles typical discrete sensor signals without cycle impact. Isolation between input groups and the internal bus is 500 V AC, and between channels 500 V AC as well. This allows the module to be used in mixed-voltage zones without bridging clearance issues. The 24 V DC sensor supply range is 19.2 to 28.8 V, which accommodates regulated or lightly-loaded supplies.","metaTitle":"Schneider TM3DI32K 32-Point Digital Input Module, 24 V DC","metaDescription":"TM3DI32K discrete input module, 32 inputs 24 V DC, IEC 61131-2 type 3, HE-10, IP20.
