The 6ES7288-1CR40-0AA1 is a compact SIMATIC S7-200 SMART CPU CR40s designed for automation control applications requiring integrated controller functionality and onboard digital I/O.
Siemens introduced the CR40s AC/DC/Relay as one of the compact serial CPU models within the S7-200 SMART family. The CR series combines CPU functionality with onboard digital signal handling in a compact controller architecture.
The CR40s belongs to the compact CPU branch of the S7-200 SMART platform, integrating controller functionality into a compact form factor.
The model designation identifies its AC-powered, DC-input and relay-output configuration.
The CR CPU family provides four high-speed counters, supporting applications where high-speed pulse counting is part of the control task.
The S7-200 SMART platform is engineered using STEP 7 Micro/WIN SMART for CPU programming and project engineering.
As an S7-200 SMART compact CPU, the CR40s is positioned for automation control tasks where the controller must process digital field signals and operate connected actuators. Its integrated architecture is particularly relevant to compact machine and equipment control systems.
The four high-speed counters available on the CR CPU models make the platform relevant to control tasks involving high-speed pulse counting, such as monitoring or counting repetitive machine events.
When an installed S7-200 SMART CR40s CPU no longer performs its controller function, maintenance teams may need the exact 6ES7288-1CR40-0AA1 order number to identify a matching replacement. A controller failure can interrupt the machine sequence, digital I/O processing and connected actuator control, potentially extending equipment downtime while the correct replacement is being sourced.
The right automation component can make the difference between extended troubleshooting and getting a machine back into service. Send us your exact requirement and let our sales team handle the sourcing process.
It is identified by Siemens as the CPU CR40s AC/DC/Relay, one of the compact serial CPU models in the S7-200 SMART platform.
The designation describes the electrical configuration of the CR40s: an AC power-supply arrangement, DC digital input circuitry and relay output technology.
Siemens identifies four high-speed counters for the new CR CPU models introduced with the S7-200 SMART V2.3 generation.
The S7-200 SMART family is engineered with STEP 7 Micro/WIN SMART.
The complete order number should be verified whenever a CR40s CPU is being replaced, because the exact designation identifies the required CPU configuration and helps avoid selecting a different S7-200 SMART CPU variant.
