Schneider Electric TM3DI16G Digital Input Module

Schneider Electric's TM3DI16G is a 16‑channel digital input expansion module for Modicon TM3 controllers, delivering 24 VDC inputs through removable spring terminal blocks. It provides 16 Type 1 (IEC/EN 61131-2) digital inputs with a single common line and supports both sink and source wiring; the nominal input voltage is 24 Vdc and each channel draws about 7 mA. The spring-terminal variant uses unshielded cable up to 30 meters in length and weighs about 100 g, with per-channel LEDs (green) indicating when an input is active. Designed to extend TM3 I/O capability, the TM3DI16G enables compact, field-wireable digital input networks and pairs with other TM3 I/O modules for scalable automation projects.
