Siemens | Simatic S7 3RK1903-1AC00

Product Details

• Part Number 1 3RK1903-1AC00

Product Description

3RK1903-1AC00 is identified by Siemens as a Terminal Module within the Simatic S7 family.

For replacement planning, its purpose is tied to the system function named for the product. Connection, configuration, and operating requirements should be confirmed from the installed equipment documentation. The assigned system function should be preserved through installation and service.

Within an S7 installation, the exact hardware order number determines supported interfaces and configuration behavior. System and software compatibility should be checked before replacement. The original equipment schedule should guide compatibility review.

When this product is used for lifecycle support, technicians should confirm the installed revision, connection arrangement, and system assignment rather than assuming interchangeability with a similarly named module. Existing connection and module records should guide replacement work.
