The outputs are current-sourcing (PNP) transistor type, rated 0.75 A per channel resistive load. That means it drives standard 24 V DC solenoids, contactor coils, and indicator lamps directly — no interposing relay needed for most loads under that current. Inputs accept +15 to +30 V for a logic \"1\" and sink about 4 mA typical. They're optocoupled between channels, with isolation tested at 500 V AC for one minute. The input filter gives you a 50 µs turn-on and 200 µs turn-off — fast enough for encoder counting up to a few kHz, but not for high-speed pulse trains. The module measures 70 mm wide by 100 mm tall by 81 mm deep. The IP20 enclosure means it's for the cabinet interior only; no washdown exposure. Outputs are arranged in groups of four and eight. The datasheet limits each group: 3 A max for a group of four, 6 A max for a group of eight, and the same derating applies up to 50 °C. So if you're driving a bank of valves, spread the load across groups — don't hang all 3 A on one four-point block. CE marking is confirmed on the listing. The module carries basic electrical isolation and ESD protection per the S7-200 SMART design. For full compliance packs (RoHS, REACH, UL), the manufacturer's declaration is available with the order documentation.","metaTitle":"Siemens 6ES7288-2DT32-0AA0 S7-200 SMART CPU, 16DI/16DO, 24 V","metaDescription":"Siemens 6ES7288-2DT32-0AA0 S7-200 SMART CPU with 16 digital inputs, 16 transistor outputs, 24 V DC.
