6ES7288-1CR40-0AA0

The SIMATIC S7-200 SMART CPU CR40 is a compact controller with integrated digital I/O, relay outputs and AC power supply capability, designed for compact automation control applications.

Integrated Digital I/O

The CR40 combines 24 digital inputs with 16 relay outputs in a compact CPU platform.

AC Supply Architecture

The CPU accepts an AC supply in the 85–264 V range with a permissible line frequency of 47–63 Hz.

Engineering Environment

Programming is carried out using STEP 7 Micro/WIN SMART within the S7-200 SMART environment.

Designed for Compact Machine Control

With integrated digital I/O and relay outputs, the CR40 is suited to compact automation architectures where a dedicated CPU is required to coordinate field signals and switching devices.

When a CR40 is being searched for during maintenance, typical triggers can include a failed CPU, loss of controller operation, abnormal I/O behavior, or the need to restore an existing S7-200 SMART control configuration.

Why the replacement matters

A controller fault can interrupt machine sequencing, digital signal processing and relay-controlled equipment. For production assets depending on this CPU, an unavailable replacement may extend troubleshooting and increase equipment downtime.
