The integrated switch passes data with a jitter maximum of 1 µs, enabling synchronized axis positioning and drive-to-drive coupling on the same ring. Isochronous mode and equidistance are both supported, making this the right choice for applications that demand deterministic timing — such as printing presses, packaging lines, or high-speed material handling. ## Power budget and thermal coordination Typical power loss is 2.4 W at 24 VDC supply. Module width is 50 mm and depth is 74 mm. The module draws its supply via the BusAdapter; no separate load supply is needed. Plan for a free BusAdapter slot if you need additional ET 200AL modules, since each interface can serve up to 16 additional modules through the BU/BA send interface. Listed as current production. Lead time and availability are confirmed via RFQ. Security level complies with Security Level 1 Test Cases V1.1.1, meeting the cybersecurity baseline for PROFINET installations in manufacturing cells.","metaTitle":"Siemens 6AG1155-6AU01-2CN0 PROFINET Interface Module, IRT 12","metaDescription":"Siemens 6AG1155-6AU01-2CN0 ET 200AL PROFINET interface module with IRT down to 125 µs, 2 ports via BusAdapter, 0.25 A²·s I2t, 2.4 W @ 24 VDC.
