The product identified as Siemens 3RK1903-2AC00 is a Terminal Block Pen in the Simatic S7 hardware family.
Within the process-control arrangement, 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. This helps preserve the function assigned to the installed control node.
SIMATIC S7 integrates programmable control, modular I/O, and industrial communication functions. This product belongs to the PLC modules layer of the installed S7 automation solution. Ratings and capacity should be verified against the exact model documentation.
For maintenance or replacement work, the exact module designation should be checked against the installed hardware, wiring records, and control-system documentation before the component is placed into service. The product should be matched to the documented control-system position.
