Accepts 120/230 V AC (47 Hz to 63 Hz) without jumpers; typical current draw per channel is 11 mA at 230 V AC. Module powers up in 500 ms — useful for fast restarts after power flickers. Rated operating range: -40°C to +70°C when mounted horizontally, -40°C to +40°C vertically. Above +60°C horizontal, the number of simultaneously controllable inputs drops from 16 to 8 — factor that into your thermal budget. ## Isolation, wiring, diagnostics Channel-to-backplane isolation tested at 2 500 V DC; between-channel groups of 4 are isolated for 250 V AC. Shielded cable runs up to 1 000 m, unshielded up to 600 m. No short-circuit detection, no wire-break alarm, no diagnostic alarm. Front-panel LEDs: green RUN, red ERROR, green per-channel status, red module diagnostic indicator. Status updates within 25 ms on rising and falling edges.","metaTitle":"6AG1521-1FH00-7AA0 Siemens 16 DI 120/230 VAC, 35mm","metaDescription":"Siemens 6AG1521-1FH00-7AA0 SIPLUS S7-1500 digital input module, 16 DI, 120/230 VAC, 35 mm width, -40 to +70 °C horizontal.
