      Information

      Overview Manuals Common Applications Product Precautions
      The Siemens 6ES7288-1CR40-0AA1 is a SIMATIC S7-200 SMART CR40s compact CPU with 24 integrated 24 V DC digital inputs, 16 relay outputs, and 20 KB of program/data memory.
      • CPU CR40s
      • 24 DI 24 V DC; 16 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 24 onboard binary input signals, and commands 16 field outputs for forty-point compact relay control without an expansion-module requirement. 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 standalone production fixtures and utility equipment.

      Important Notice: Use the complete 6ES7288-1CR40-0AA1 code and verify the physical nameplate, firmware, project, accessories, and current Siemens documentation before installation or replacement.
