It sits on the S7-1500 mounting rail, 35 mm wide, and draws its 24 V DC supply from the backplane bus (L+ with -0.8 V tolerance). The module offers 8 outputs that can be parameterized as standard (5 µs switching) or high-speed (1 µs switching with a 240 Ω lower impedance limit). With isochronous mode, it synchronizes output updates to the bus cycle for motion or high-speed logic. Four integrated counters handle pulse trains from encoders or 24 V initiators. Onboard RUN (green), ERROR (red), and MAINT (yellow) LEDs give immediate field status. Diagnostic alarms fire on wire-break or short-circuit, reducing guesswork at startup. The module is in active current production – no lifecycle concerns for your BOM. ## Mounting & wiring notes 35 mm width; depth 129 mm. Unshielded cable runs up to 600 m depending on load and cable quality; shielded runs up to 1 000 m. Parameterizable filter from 0.05 to 0.8 ms, per group of 8.","metaTitle":"Siemens 6ES7552-1AA00-0AB0 S7-1500 Digital I/O Module, 24V,","metaDescription":"Siemens 6ES7552-1AA00-0AB0 digital I/O module for S7-1500; 24V supply (L+ -0.8V), 8 outputs, 1 µs jitter, isochronous mode, diagnostic alarms.
