Why Choose the WAGO 750-650/000-002 RS-232 Serial Interface Module?
The WAGO 750-650/000-002 is a versatile RS-232 serial communication interface module designed for seamless integration within the WAGO I/O System 750. It enables PLC controllers and automation systems to communicate with devices that utilise standard RS-232 serial interfaces such as barcode scanners, printers, laboratory instruments and industrial measurement equipment.
The module provides reliable full-duplex serial communication using recognised standards including TIA/EIA-F and CCITT V.28. This ensures compatibility with a wide range of serial devices commonly used across manufacturing, data acquisition and automation systems.
Installed as part of a modular WAGO fieldbus node, the interface allows legacy serial devices to be integrated directly into distributed PLC architectures without requiring external gateways or converters.

Serial Communication in Industrial Automation
RS-232 serial communication remains widely used for connecting specialised industrial equipment and legacy instrumentation. Many devices such as barcode scanners, weighing systems and laboratory analysers still rely on serial communication for reliable data transfer.
The WAGO 750-650/000-002 enables these serial devices to be integrated directly into PLC-based control systems. By transferring serial data through the WAGO fieldbus controller, engineers can combine legacy equipment with modern automation platforms and centralise process monitoring.
Typical Applications
- Connecting barcode scanners and industrial printers.
- Integrating weighing systems and measurement instruments.
- Communication with legacy RS-232 industrial devices.
- Factory data acquisition systems.
- Industrial monitoring and diagnostics.
