It accepts line frequencies from 47 to 63 Hz; at nominal 60 Hz each channel draws 12 mA, or 10.7 mA at 50 Hz. The input impedance of 2600 Ω capacitive at 60 Hz (3100 Ω at 50 Hz) presents a light load to the source transformer, suitable for long AC runs in cold storage or freezer areas where signal transformers may be undersized. ## Noise margins and isolation Channel-to-bus and channel-to-channel isolation rated 1780 Vrms for one minute. Maximum leakage current is 1.9 mA. ## Response timing and diagnostics Response time is line-cycle-dependent: Off-On ranges from 4.9 ms (60 Hz) to 0.75 ms (50 Hz); On-Off from 7.3 ms to 12.3 ms. The module adapts timing to the detected line frequency, so a 50/60 Hz system swap does not require reconfiguration. Sixteen green LEDs per input and a green bus-active LED give immediate visual feedback for on-site troubleshooting. A red LED signals an external fault. ## Sourcing posture Available to order against an RFQ. Since it is an active Quantum family module, lead times are standard factory build cycles.","metaTitle":"Schneider Modicon 140DAI34000 Quantum 16-Point 24VAC Input M","metaDescription":"Active 16-point 24V AC discrete input module, 12 mA per channel, 1780 Vrms isolation.
