Each input is sink or source configurable, draws 7 mA at the rated voltage, and has a 3.4 kΩ input impedance. The response time is 4 ms for both state 0 and state 1 transitions. ## Mounting and connection It ships with one removable screw terminal block for field wiring. Physical footprint: 23.5 mm wide, 84.6 mm deep, 90 mm tall. The kit includes the module and terminal block — no hidden add-ons needed for a clean install.","metaTitle":"Schneider TM2DDI8DT 8-Channel Input Module, 24 V DC","metaDescription":"Obsolete Modicon M238 8-input 24 V DC module, 4 ms response, DIN rail mount.
