Product Details

• Part Number 1 6ES5374-2AH21

Product Description

Siemens 6ES5374-2AH21 is a Memory Module for the Simatic S5 product family.

Memory and storage components retain program, configuration, or operating information used by compatible automation hardware. Capacity, data type, and retention behavior depend on the exact module design. The original equipment schedule should guide compatibility review.

In a SIMATIC S5 system, module selection is governed by the controller family, rack arrangement, electrical interface, and configured program. The exact article number should be matched before installation. The installed revision should be confirmed before the product is applied.

In the signal path, this approach helps preserve the intended system function while keeping selection aligned with the documented ratings, capacity, and compatibility requirements. The system's documented hardware assignment should guide placement.
