      Overview Manuals Common Applications Product Precautions
      The Siemens 6ES7288-1CR20-0AA1 is a SIMATIC S7-200 SMART CR20s compact CPU with 12 integrated 24 V DC digital inputs, 8 relay outputs, and 20 KB of program/data memory.
      • CPU CR20s
      • 12 DI 24 V DC; 8 relay DO
      • 85 to 264 V AC at 47 to 63 Hz
      • 20 KB program/data memory

      It executes the STEP 7 Micro/WIN SMART user program, reads the 12 onboard binary input signals, and commands 8 field outputs for entry-level compact relay control with twenty onboard I/O points. Its relay channels switch approved AC or DC loads within the published contact limits. The compact CRs design uses integrated RS485 communication and fixed onboard I/O. It is suited to simple pumps, fans, and compact machine panels.

      Important Notice: Use the complete 6ES7288-1CR20-0AA1 code and verify the physical nameplate, firmware, project, accessories, and current Siemens documentation before installation or replacement.
