The Siemens 6ES7193-4CD20-0AA0 is a SIMATIC DP Terminal Module TM-P15S23-A0 used in ET 200S distributed I/O systems to connect power modules. It occupies a 15 mm slot on the DIN rail and provides screw terminals for up to 2x3 connections, with access to the AUX1 bus bar (interrupted). At 43 mm deep and 132 mm tall, it fits the standard ET 200S backplane envelope and mates with the existing power module's bus connectors without modifying the rack layout.
The module clips onto the standard ET 200S mounting bracket and provides screw terminals with 2x3 connections; the AUX1 bus is interrupted on this variant. Upstream and downstream power segments must be jumpered externally if continuous AUX1 is required.
