Information About 750-301
The 750-301 is part of the WAGO I/O System 750 fieldbus coupler family and is engineered for PROFIBUS DP/FMS communication. It automatically detects all connected I/O modules and creates a local process image that supports analog, digital, and specialty modules. Analog and specialty data are transferred word- or byte-based, while digital signals are packed bit by bit and aligned automatically within the process image. Designed for DIN-rail mounting, the coupler integrates power distribution, electrical isolation, and standardized PROFIBUS connectivity for industrial control environments.
Key Features:
- PROFIBUS DP Interface: Connects the WAGO I/O System as a slave device to PROFIBUS networks.
- Automatic Process Image Creation: Detects installed modules and builds a structured local process image.
- Mixed I/O Data Handling: Supports analog, digital, and specialty modules within a single node.
- Flexible Data Mapping: Transfers analog data as words or bytes and digital data bit by bit.
- High I/O Capacity: Supports up to 6000 I/O points depending on the PROFIBUS master.
- Reliable Serial Communication: Operates at baud rates up to 1.5 Mbit/s.
- Integrated Power Distribution: Supplies system and field power via internal jumper contacts.
- Electrical Isolation: Provides 500 V isolation between system and field supplies.
- DIN-Rail Mount Design: Compact housing optimized for control cabinet installation.
The 750-301 delivers the reliability and precision required for PROFIBUS-based distributed I/O and industrial automation systems.
