Each group of 4 channels shares isolation at 500 Vrms, and the bus isolation is rated 1780 Vrms. Addressing takes 2 input words, and the guaranteed state-1 current is 4 mA at a threshold below 0.8 V DC. The module is CE marked and listed under UL 508 and CSA C22.2 No 142. It includes conformal coating (Humiseal 1A33) for environmental protection, and status indication via 32 green LEDs per input plus bus/fault LEDs. The 5 V TTL DC input range (4.5...5.5 V) with negative logic means the module expects sourcing (PNP) sensors that pull the input low to activate. Guaranteed state-1 voltage is 0.8 V DC or lower; state-0 is ≥4 V at 5.5 V supply. Response time ≤500 µs from state 1 to 0 covers fast signals like encoder zero pulses or proximity edges without missing transitions in a typical 10 ms scan. Power dissipation of 5 W should be considered in dense rack populations for thermal ambient temperature limits of 0–60 °C. Group-to-group isolation at 500 Vrms allows mixing separate sensor supply commons per group without risk of ground loops. The absolute maximum continuous input is 5.5 V; a 15 V decaying pulse up to 1.3 ms is tolerated for transient protection.","metaTitle":"Schneider 140DDI15310C Quantum 32-pt 5V TTL Input, 500µs Res","metaDescription":"140DDI15310C Modicon Quantum 32-point 5V TTL DC negative-logic discrete input module.
