What this terminal module does in the ET200S motor starter stack
The 3RK1903-0AG01 is a TM-XB215 S24-01 terminal module that mounts to the right of RS1-X, DS1-X, RS1E-X, DS1E-X, F-DS1E-X, F-RS1E-X, or DSS1E-X motor starters in the ET200S system — it provides the connection point for brake control modules XB3, XB4, or XB6 without needing its own XB4/6 slot. This module is part of the SIRIUS family and sits in the Remote I/O & Fieldbus Modules category, meaning it integrates into a PROFIBUS or PROFINET ET200S station as a distributed I/O slice.
Lifecycle and compliance — active production, RoHS dated
Substance Prohibitance date is 05/01/2012, which aligns with the RoHS compliance cutoff for the European directive — the module meets the restricted-substance limits effective from that date.
