PULS YR40.242 DIN-Rail Redundancy Module 40A 9-30VDC 2-Input 1-Output

Handle up to 40 A output current with a maximum voltage drop of just 0.4 V using the PULS YR40.242 DIN-rail redundancy module. This diode-based decoupling unit accepts two independent 24 VDC power supplies and combines them into a single output, enabling N+1 or N+M redundancy for critical loads.

Overview

The YR40.242 is designed for 24 VDC systems and supports an input voltage range of 9–30 VDC. It features two inputs and one output, with screw terminals for secure wiring. The module mounts on a standard 35 mm DIN rail and operates in temperatures from -25 °C to +70 °C.

What stands out

• High current capacity: 40 A output with low voltage drop
