Input response settles in 4 ms on either edge, and the 4.4 kOhm impedance limits current draw to roughly 5 mA per point at nominal voltage. All 16 inputs share one common, keeping the field wiring simple. Isolation between channels and internal logic is tested to 500 V for one minute. The module pulls 35 mA from the 5 V backplane when all inputs are at state 1. ## Panel Fit & Field Notes Occupies a single-wide slot — width 21.4 mm (0.8 in), depth 81.3 mm (3.2 in), height 90 mm (3.5 in). The HE10 connector handles field wiring; a matching cable or breakout board is needed for screw-terminal connection. Two display blocks on the front show per-channel status at a glance.","metaTitle":"Schneider TM2DDI16DK 16-Input DC Module, Obsolete","metaDescription":"Schneider TM2DDI16DK 16-point 24 VDC sink/source input module for Modicon M238.
