Item no. 750-333/040-000
Fieldbus Coupler PROFIBUS DP; 2nd Generation; 12 MBd; Extreme


The 750-333 Fieldbus Coupler maps the peripheral data of all the I/O modules of the WAGO-I/O-SYSTEM on PROFIBUS DP.

When initializing, the coupler determines the node's module structure and creates the process image of all inputs and outputs. In order to optimize addresses, the I/O modules with a bit width smaller than 8 are grouped in one byte.

It is furthermore possible to deactivate I/O modules and to modify the image of the node according to the connected signals without having to modify the existing application.

The diagnostic concept is based on ID- and channel-related diagnostics according to EN 50170. This does away with the need for programming modules to evaluate manufacturer-specific diagnostic data.

The module is ideally suited for operation in harsh environmental conditions:
- strongly extended temperature range
- higher dielectric strength and EMC resistance
- higher vibration and shock resistance
