What This 140DAI74000 Is
The 140DAI74000 is a 16-channel 230 VAC discrete input module from the Modicon Quantum automation platform. It accepts 230 V AC inputs, draws 11.5 mA at 57–63 Hz or 9.7 mA at 47–53 Hz, and provides isolation of 1780 Vrms between channels and bus. The module is marked CE and carries UL 508 and CSA C22.2 No 142 approvals.
Key Ratings That Drive Fit
16 inputs map to 1 input word. Input current: 11.5 mA at 57–63 Hz or 9.7 mA at 47–53 Hz; response: 4.9–0.75 ms Off-On, 7.3–12.3 ms On-Off; max input 264 V continuous; leakage ≤2.6 mA.
Physical & Environmental Notes
The module draws 180 mA from the Quantum backplane bus, dissipating 5.5 W maximum. Operates from 0 to 60 °C ambient; storage from -40 to 85 °C. Humidity tolerance up to 95% without condensation. Altitude rated to 5000 m. Local diagnostics via one green LED for bus active, one red LED for external fault, plus 16 green input status LEDs — no scope needed to spot a missing input.
