Why Choose the WAGO 750-626/020-002 Potential Distribution Module?
The WAGO 750-626/020-002 is a specialised potential distribution module with diagnostic functionality designed for the WAGO I/O System 750 and 753. It distributes the 24 V DC field supply across modular I/O systems while simultaneously monitoring the electrical insulation of the field supply network.
In addition to reliable power distribution, the module provides ground fault detection for the connected field supply. This diagnostic capability enables early detection of insulation faults, improving system reliability and supporting safety requirements in demanding industrial applications.
The module distributes power using internal power jumper contacts and provides additional field wiring terminals via CAGE CLAMP spring terminals. Its compact DIN rail design ensures seamless integration within modular automation nodes.
