Schneider Electric TM3DI16G Discrete Input Module

Schneider Electric TM3DI16G is a 16-channel discrete input expansion module for Modicon TM3 controllers, delivering 24 V DC digital inputs with sink or source logic via removable spring-terminal blocks. It supports Modicon M221, M241, M251 and M262 controllers, provides a single common input line, and includes a green status LED on each channel to indicate activity, with unshielded wiring rated up to 30 m between devices. The compact form measures 27.4 mm wide, 90 mm high, and 84.6 mm deep (≈100 g) and can be mounted on IEC TH35 rails (TH35-15 or TH35-7.5) or on a plate with a fixing kit, rated IP20. Electrical specs include 24 V DC nominal input, 16 inputs, 3.4 kΩ input impedance, and state guarantees: ON 15–28.8 V, OFF 0–5 V, with per-input current ≥ 2.5 mA.
