Siemens 6ES7-194-1KA01-0XA0 Connector

Siemens 6ES7-194-1KA01-0XA0 is a SIMATIC DP Y-connector for ET 200 distributed I/O, designed to act as a passive interconnect that splits a single DP cable into two I/O branches for ET 200 modules. Officially cataloged as 6ES7194-1KA01-0XA0, the unit uses 5‑pin M12 connectors to link the PROFIBUS DP bus with the two ET 200 I/O lines, enabling double connections from one cable. This accessory is used in PROFIBUS DP networks to expand ET 200 distribution without running a second DP cable, making it a practical choice for compact automation layouts where cable routing and space are at a premium. In catalog listings you may encounter variations such as E02 for this Y-connector, but the core function remains the same: a DP Y-connector that facilitates a twin I/O feed from a single ET 200 DP connection.
