Wago 750-621 Separation module with power jumper Contacts

Why Choose the WAGO 750-621 Distance Module?

The WAGO 750-621 is a versatile distance and separation module designed for the WAGO I/O System 750 and 753. It allows engineers to visually and electrically divide sections of a fieldbus node while maintaining reliable internal system communication between modules.

Part of the WAGO automation product range, the module simplifies the structure of modular I/O assemblies. By creating clearly defined sections within the automation node, it improves system organisation, troubleshooting and maintenance in distributed PLC control systems.

Unlike standard separation modules, the 750-621 includes integrated power jumper contacts. These contacts allow the module to continue supplying field power to adjacent modules while still providing physical separation within the I/O station. :contentReference

Industrial Automation System Organisation

Large distributed automation systems often contain numerous I/O modules connected to a single fieldbus coupler or PLC controller. Distance modules help engineers organise these assemblies by dividing a station into logical sections while maintaining communication through the internal system bus.

The WAGO 750-621 performs this separation while continuing to transmit field power to adjacent modules through its jumper contacts. This allows system segmentation without interrupting power distribution within the automation node. :contentReference

Typical Applications

• Distributed PLC and fieldbus I/O systems.
• Industrial control cabinets and automation panels.
• Machine automation and manufacturing equipment.
• Large modular I/O stations requiring structured segmentation.
• Automation systems requiring organised wiring layouts.
