Technical Overview

DIN-35 rail-mount potential distribution module with 4 isolated potentials and 19 connection points per potential. The unit is rated for operating voltages up to 250 VAC/VDC, with up to 12 A per connection and 32 A total current per potential. It uses CAGE CLAMP® spring-pressure termination technology and combines a power supply connection based on WAGO 745 Series interfaces with distribution connection points based on WAGO 739 Series interfaces. The module supports solid and fine-stranded conductors from 0.2 to 6 mm² on the power supply side and 0.08 to 2.5 mm² on the connection-point side. It is designed as a mounting carrier for DIN-35 rail installation and specified for operation from -20 to +50 °C.

Industrial Applications

1. 24 VDC control potential distribution in machine control panels

Use the module to fan out multiple 24 VDC control supply potentials across terminalized field circuits in a DIN-rail cabinet. With 4 separate potentials and 19 connection points each, it supports organized segregation of supply groups such as sensors, actuators, interlocks, and auxiliary control loads.

Problem Solved

Reduces panel wiring congestion and eliminates ad-hoc splicing when many field devices need structured distribution from several independent supply potentials.

2. Multi-potential distribution for building and process I/O marshalling

Suitable for marshalling cabinets where several commons or supply potentials must be distributed cleanly to many terminations. The 45° mating direction and CAGE CLAMP® terminations support high-density cabinet wiring while accommodating both solid and fine-stranded conductors.

Problem Solved

Provides a compact and serviceable way to distribute several isolated potentials to numerous field terminations without separate busbar assemblies or multiple smaller terminal blocks.

3. Power distribution grouping for test benches and interface racks

In electrical test fixtures or interface racks, the module can distribute up to 250 VAC/VDC across grouped circuits while maintaining defined current limits of 12 A per connection and 32 A per potential. Its DIN-rail format makes it easy to integrate into modular lab or industrial racks.

Problem Solved

Creates repeatable and maintainable grouped power distribution for many test or interface points while preserving separation between multiple potentials.
