DIN-rail redundancy-module reference for coordinating multiple DC supply paths.

## In plain English

### What it does

A power-supply redundancy module combines suitable supply paths so the connected load can remain powered if one source is lost, within the designed arrangement.

### A simple example

In a substation control panel, it can connect two independent DC supplies to a common supported load.

### What the drawings help you do

Use the selected manufacturer's drawings to check the equipment's size, mounting points and cable connections. The layout helps you plan where it fits and how it can be reached for maintenance. An illustrative 3D preview does not establish product dimensions or required clearances.

### Terms

- Schematic: A drawing showing function and connections rather than physical appearance.

## What it represents

Place the module where supply inputs and the combined load output can be identified and maintained. Draw the supply connections in the schematic, not as assumed links in the GA.
The downloadable GA illustration is independently authored conceptual geometry, with no scale or manufacturer dimensions. Use the official CAD source for the exact layout.
Altech originals remain at the manufacturer source because their drawing notices restrict reproduction. Product lifecycle and availability have not been established.

## How to read it

- Reserve access to all power terminals and keep each incoming supply labelled.
- A redundancy module is not a battery backup module and does not by itself guarantee uninterrupted power.

## Information to show or reference

- Confirm PSC-RM20 identity.
- Separate and label source and load cable routes.
- Verify ratings, wiring and lifecycle in manufacturer documentation.

## Important distinction

A redundancy module is not a battery backup module and does not by itself guarantee uninterrupted power.
