What this module does in a Siemens network
The Siemens 6GK1102-0AB00 is a PLC expansion module that sits in the Industrial Networking category — it extends the communication or I/O capacity of a Siemens controller rack without swapping the CPU.
Specs that matter for panel integration
Rated for the Siemens Industrial Networking family, it uses the backplane connector to draw power and exchange data with the CPU — no separate field power supply required for the module itself.
