Siemens 6ES5374-2FH21 is a long-format SIMATIC S5 memory card. It uses 256 KB Flash EPROM memory with 16-bit organization and is intended for legacy S5 systems where compatibility depends on the installed CPU and hardware configuration.
When replacing a memory card, capacity alone is not enough to identify the correct part. The 374 family includes cards with different form factors, memory technologies and programming requirements. Compare the complete catalog number with the card removed from the controller or with the machine documentation.
SIMATIC S5 documentation is available from Siemens Industry Online Support. Other 374-series cards in the POLRAD catalog include 6ES5374-2KH21 and 6ES5374-1KH21.
If you are selecting a card for an existing CPU, send us the controller designation and the number from the old card. This helps avoid ordering a similar but incompatible version.
