Why Choose the WAGO 750-622 Binary Spacer Module?
The WAGO 750-622 is a versatile binary spacer module designed for the WAGO I/O System 750 and 753. It allows engineers to reserve digital I/O addresses within a fieldbus node while also providing field-side power distribution for downstream modules.
Part of the WAGO automation product range, the module supports flexible system configuration by allowing PLC programmers to allocate digital addresses in advance, even when no physical I/O device is installed. This simplifies system expansion and ensures compatibility with future automation upgrades.
The module also functions as a field power supply pass-through, distributing the 24 V DC field voltage to downstream I/O modules via integrated power jumper contacts. This dual functionality makes the 750-622 particularly useful when planning scalable modular automation architectures. :contentReference

Industrial Automation System Configuration
In modular automation systems, engineers often need to reserve PLC addresses for future expansion or maintain compatibility with pre-existing control programs. Binary spacer modules allow these addresses to remain allocated even when no physical I/O module is installed.
The WAGO 750-622 provides this capability while continuing to distribute field-side power to downstream modules. This approach ensures that automation systems remain scalable, maintainable and adaptable to future equipment upgrades. :contentReference
Typical Applications
- Distributed PLC and fieldbus I/O systems.
- Automation systems requiring reserved digital I/O addresses.
- Machine control systems with planned future expansion.
- Industrial control cabinets and modular automation nodes.
- Manufacturing and process automation systems.
