It's the wiring interface that connects the reversing starter's control and power circuits to the ET 200S distributed I/O system — think of it as the breakout point for the motor branch. No separate supply line connection means the module draws its power from the ET 200S bus — one less wire to pull. For a line-down swap, the terminal assignments match the standard ET 200S RS footprint; pull the old module, clip the new one in, and re-terminate the motor and control cables.","metaTitle":"Siemens 3RK1903-0AC10 Terminal Module for ET 200S RS Reversi","metaDescription":"Terminal module for ET 200S RS reversing starter without supply line connection.
