What this terminal module does on an ET 200S slice
The 6ES7193-4CB70-0AA0 is a TM-E15N24-01 terminal module for the Siemens ET 200S distributed I/O system — it carries the electronic module (I/O slice) and provides the field wiring interface via FastConnect push-in terminals, 2x4 connections per module, with AUX1 solid (no separate terminal access to the auxiliary bus). Each packing unit delivers 5 modules, so a 16-slice rack needs three units with one spare. The 15 mm width matches the standard ET 200S electronic module footprint — it snaps onto the DIN rail and the backplane bus connector passes through.
Dimensions are 15 mm wide, 162 mm tall, 43 mm deep — the height is the DIN-rail span, so the module occupies one ET 200S slot position and leaves room for the wiring duct below the rail. FastConnect termination means the field wires punch down without stripping — the insulation-displacement contact cuts through the jacket as you push the wire in, saving time on a multi-drop cabinet build. AUX1 solid means the auxiliary bus bar is continuous through this module; no bridging jumper needed for the AUX1 rail.
Sourced to order against the BOM quantity through independent distribution channels. The 5-unit packing unit means you order in multiples of 5; a single module is not available separately.
