WAGO 750-344/000-004 InterBus Eco Fieldbus Coupler
Compact fieldbus coupler for distributed I/O in InterBus network installations
Overview
The WAGO 750-344/000-004 is an InterBus Eco fieldbus coupler that connects WAGO's modular I/O system to an InterBus fieldbus network. It supports up to 256 fieldbus nodes on the master and up to 4,096 I/O points across the network, with a bus segment length of up to 400m at a 500 kBd baud rate. Each coupler can support up to 64 modules per node, with process image capacity of up to 20 bytes each for input and output. Operating on a 24VDC system supply, this coupler is a key building block for distributed I/O installations within an InterBus-based automation system.
Key Features
- Large network capacity: Supports up to 256 fieldbus nodes on the master and up to 4,096 I/O points system-wide.
- Extended bus segment reach: Maximum bus segment length of 400m, supporting distributed installations across larger facilities.
- Fast transmission: 500 kBd baud rate with a transmission time of 1.43 ms for responsive I/O updates.
- High module capacity per node: Supports up to 64 modules connected to a single node.
- Standard process image size: Up to 20 bytes each for input and output process image data.
- Standard 24VDC supply: Compatible with common industrial control system power supplies.
