The 750-375 is an advanced fieldbus coupler designed to connect the WAGO I/O System 750 to PROFINET IO industrial ETHERNET networks. It operates as an I/O device with a baud rate of 10/100 Mbit/s and features an integrated 2-port switch, simplifying the creation of a line structure without additional network components. The coupler supports up to 250 I/O modules, manages a process image of up to 512 bytes each for inputs and outputs, and operates on a 24 VDC system supply. This device automatically identifies connected I/O modules, making it a flexible solution for building complex automation systems with mixed analog and digital signals.
