Signal thresholds are defined: a logic 0 is below 5 V DC, and a logic 1 spans +15 to +30 V DC, with a typical input current of 4 mA per channel at 24 V. The module draws a typical power loss of 1.5 W from the backplane. Response time is symmetrical at 200 µs for both off-to-on and on-to-off transitions, suitable for fast discrete sensing on a conveyor or packaging line. Inputs can be wired in groups of two, and parallel switching of inputs is permitted — useful for paralleling contacts from multiple sensors into one channel. ## Panel fit and wiring constraints The IP20 rating means it belongs inside an enclosure, not on the open line side. Unshielded sensor cable runs are limited to 300 m; shielded runs can extend to 500 m. Supply tolerance is 20.4 to 28.8 V DC, so a regulated 24 V supply is recommended.","metaTitle":"6ES7288-2DE08-0AA0 SIMATIC S7-200 SMART 8 DI, 24 V DC","metaDescription":"SIMATIC S7-200 SMART digital input module SM DI08, 8 digital inputs 24 V DC sink/source, 1.5 W typ, IP20, CE marked.
