It reads 230 VAC field signals and presents them as two input words to the backplane. Each input group of four channels is optically isolated to 1780 Vrms from the bus and from other groups, so you can mix voltage references across groups without worry. Input current draws 11.5 mA at 57–63 Hz or 9.7 mA at 47–53 Hz. The guaranteed ON state starts at 165 VAC for 57–63 Hz, 175 VAC for 47–53 Hz; OFF state is below 40 VAC. Response time depends on line frequency: Off-ON is 4.9 to 0.75 ms per line cycle, ON-OFF is 7.3 to 12.3 ms. Keep these in mind if you're scanning faster than one line cycle — the module won't respond faster than the input filter allows. Absolute maximum input is 264 V continuous, 312 V for 10 s, 400 V for one cycle. Conformal coated with Humiseal 1A33 and rated for 95% humidity without condensation, up to 5000 m altitude. Bus current requirement is 250 mA; power dissipation 5 W. Keep the ambient between 0 and 60 °C operating; storage handles -40 to 85 °C. For compliance documentation: the module carries CE marking and is listed under UL 508 and CSA C22.2 No 142. That should satisfy most North American panel certification requirements.","metaTitle":"Modicon 140DAI75300C 32-Input 230VAC Module, UL/CSA","metaDescription":"Obsolete Modicon Quantum 140DAI75300C discrete input module, 32 inputs at 230 VAC.
