Siemens AG 6ES7 193-4CG30-0AA0 Terminal Module

The Siemens 6ES7 193-4CG30-0AA0 Terminal Module, listed as TM-E30C44-01 for the ET 200S distributed I/O family, is a backplane-mounted interface that provides the terminal connections needed to attach field wiring to the ET 200S backplane within a SIMATIC DP network. Siemens’ documentation describes the 6ES7 193-4CG30-0AA0 variant as a terminal module for electronic modules and notes its pass-through capability for the auxiliary (AUX) rail to the adjacent potential group on the left, a feature used to maintain common distribution across neighboring modules. With the order number 6ES7 193-4CG30-0AA0, this module supports ET 200S configurations by delivering essential terminal interfaces for connected devices while integrating with the DP backplane, and it is marketed by distributors specifically as a Siemens terminal module for ET 200S I/O expansions. Typical applications include compact automation setups where ET 200S I/O blocks collect sensor inputs and drive actuators, enabling modular expansion within a standard Siemens DP/ET 200S network.
