Product details

CPU with integrated I/O and fieldbus

The Siemens 6ES7288-1SR30-0AA1 is an S7-1200 CPU with 18 kbyte program memory, 144 bytes each of digital and analog input/output mapping. It supports LAD, FBD, STL, and RAM programming, and includes a real-time clock with 7-day backup. The CPU handles up to 8 PID control loops and offers 6 high-speed counters (5 at 200 kHz, 1 at 30 kHz) for single-phase, plus 4 A/B phase counters (3 at 100 kHz, 1 at 20 kHz). Communications include TCP/IP, PROFIBUS via a CM DP module, and RS485 at up to 187.5 kbps. Transformer isolation at 1500 V AC separates the logic from the field wiring.

No lifecycle status is on record for this order code. The CE mark is listed, but no UL or other agency approvals appear in the specification record.
