PULS DIMENSION DIN-Rail Redundancy Module 1.3 A (YRM2.Diode)

In industrial automation, a single power supply failure can bring down an entire control system. The PULS DIMENSION YRM2.Diode redundancy module solves this by decoupling two power supplies, ensuring that if one fails, the other continues to power the load without interruption. This diode-based module is ideal for building 1+1 redundant power systems in compact DIN-rail installations.

Who is it for

System integrators, panel builders, and maintenance engineers who need to increase the availability of critical 24V DC circuits. It is particularly suited for applications where space is limited and a simple, reliable redundancy solution is required.

Tips

To build a redundant system, connect two independent power supplies to the input terminals of the YRM2.Diode. Ensure that each power supply can deliver the full load current, as the module will draw from the one with the higher output voltage. The diode decoupling prevents reverse currents, protecting the power supplies from back-feeding.
