Designed for the Quantum backplane, it occupies 2 input words with a bus current draw of 330 mA. Input voltage range 19.2...30 V, response ≤1 ms from state 1 to state 0. Each group of 4 channels carries 500 Vrms isolation between groups, and 1780 Vrms between group and bus. ## Compliance & Protection Listed under UL 508 and CSA C22.2 No 142, marked CE. Input protection is resistor-limited; conformal coating (Humiseal 1A33) protects against humidity up to 95% without condensation. Electromagnetic compatibility tested: 4 kV contact / 8 kV air ESD, 10 V/m RF field up to 2000 MHz. ## Diagnostics & Indicators Front panel includes 32 green LEDs for input status, one green LED for bus communication (Active), and one red LED for external fault (F). Addressing requires 2 input words in the Quantum backplane.","metaTitle":"Modicon Quantum 140DDI35310C 24VDC 32-In Input Module, Obsol","metaDescription":"Obsolete 32-point negative logic input module for Modicon Quantum. 24 VDC, source-type, UL/CSA listed.
