Information About 750-312
The 750-312 is a MODBUS RTU fieldbus coupler within the WAGO I/O System 750 series, engineered for distributed automation architectures. It supports mixed I/O configurations, enabling simultaneous handling of analog word-based data and digital bit-based signals within a single node. The coupler automatically organizes process images based on the physical order of connected I/O modules, ensuring deterministic data mapping. Designed for industrial control panels and DIN-rail mounting, it integrates power distribution, communication management, and system diagnostics in a compact housing.
Key Features:
- MODBUS RTU Communication: Operates as a slave device on RS-485 networks using MODBUS RTU protocol.
- Flexible I/O Expansion: Supports digital, analog, and specialty I/O modules within the 750/753 series.
- High I/O Capacity: Handles up to 6000 I/O points for scalable automation systems.
- Automatic Process Image Creation: Organizes data according to the physical sequence of installed modules.
- Integrated Power Distribution: Supplies system and field power via internal power jumper contacts.
- Robust Electrical Isolation: Provides 500 V isolation between system and field supply for enhanced safety.
- Wide Operating Temperature Range: Suitable for industrial environments from 0 to 55 °C during operation.
- DIN-Rail Mountable Design: Compact form factor for efficient installation in control cabinets.
- Certified Industrial Compliance: Meets CE and marine-related EMC and vibration standards.
The 750-312 delivers the reliability and precision required for distributed industrial control and MODBUS-based automation systems.
