It operates from -40 to 70 °C, drawing 4.9 W from the backplane, and needs a 40-pin front connector. The module operates -40 to 70 °C with input thresholds 0-40 V for signal '0' and 79-264 V for signal '1', transition time max 25 ms, and each input isolated per group of 1 via optocoupler. This module expands on the DIN rail via a 40-pin connector; the controller auto-assigns I/O address. At 40 mm wide, it occupies one slot with a green LED per channel for loop check.","metaTitle":"Siemens 6AG1321-1FF10-7AA0 SIPLUS SM 1221, 8 DI AC, -40…70°C","metaDescription":"8 digital inputs, AC 120/230 V, -40 to 70 °C, UL/CE/EAC.
