Siemens 6ES7 194-4BD00-0AA0 ET 200PRO Connection Module

Siemens 6ES7194-4BD00-0AA0 is the ET 200PRO Connection Module (CM) for the PM‑E power module in the ET 200PRO decentralized I/O system. Specifically designed for PM‑E 7/8" configurations, this CM plugs onto the DC24V PM‑E power module and provides four M12 field connectors to link the PM‑E to the ET 200PRO I/O network. As part of the ET 200PRO family, the CM PM 7/8" delivers a compact, modular interface that couples power distribution to the I/O system, and Siemens lists the part as 6ES7194-4BD00-0AA0 with the product name CM IO 4 x M12. Compatible with PM‑E and 7/8" PM modules in ET 200PRO installations, it is used wherever a dedicated PM‑E interface to the IO network is required, reducing wiring complexity and enabling straightforward field assembly.
