It provides the supply line connection and includes physical coding for shutdown groups — meaning the module itself enforces which group of safety outputs are tied together, preventing miswiring during panel assembly or field swap-out. This is a panel-integration part, not a standalone relay; it snaps onto the same DIN rail as the F-RS1E-X base unit and extends the wiring interface for grouped safety circuits.","metaTitle":"Siemens 3RK1903-3AD00 Terminal Module for F-RS1E-X, 130 mm","metaDescription":"Siemens 3RK1903-3AD00 130 mm terminal module for F-RS1E-X safety relay with supply line connection and shutdown group coding.
