Product Details
- Part Number 1 3RK1903-1CB00
Product Description
For Simatic S7 system applications, Siemens 3RK1903-1CB00 provides the function of a Siguard Connection Module.
For replacement planning, this component performs the specialized system function identified by its product designation within the associated automation platform. Its exact capabilities are determined by the installed configuration and product revision. Its role should remain distinct from that of similarly named assemblies.
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.
