For 0.8 ms delay, shielded cable is mandatory. At 55°C horizontal, all 16 inputs are usable; derating applies above 40°C vertical (45°C max). ## Integration notes Backplane bus draws 155 mA at 5 V DC; load voltage L+ draws 130 mA plus 6 mA per active input plus any Vs1/Vs2 current. Power loss is 7 W typical. Supply range 20.4–28.8 V DC; no NEC Class 2 required. CE, cULus, and FM approved; SIL documentation available for safety-critical loops.","metaTitle":"Siemens 6ES7226-6BA32-0XB0 16DI Safety, -40..70°C","metaDescription":"Active Siemens S7-1200 SM 1226 input module: 16 DI (24V DC), SIL2/3, PL d/e, -40 to 70°C, cULus/CE/FM.
