16 isolated AC inputs at 200–240 V
The Schneider BMXDAI1615 is a discrete input module in the Modicon X80 range. It offers 16 isolated inputs, each accepting 200–240 V AC at 3 mA. Wiring is two- or three-wire, positive logic (sink). Isolation between channels and to the backplane bus is rated 1780 Vrms for 1 minute. That per-channel dielectric strength means you can mix phases on adjacent inputs without worry. Activation response is 10 ms, deactivation 20 ms. Voltage detection thresholds: below 80 V AC flags a sensor fault, above 170 V AC is a valid 1.
