Additional Information

A safe redundant system results from the parallel connection of two decoupled power supplies. 

The POWER RDN DIO-20 is a high-performance industrial DIN rail redundancy module utilizing diode-based redundancy technology for reliable power distribution. Designed for 24V DC industrial systems, this module supports N+1 redundancy configurations with dual input channels rated at 20A each, ensuring continuous operation even in the event of primary power supply failure.

Key Technical Features:

  • Wide Input/Output Range: 9-60 VDC operation supporting 12V, 24V, and 48V nominal voltages

  • Diode-Based Redundancy: Reliable diode technology with typical voltage drop of 0.65V (Vin-Vout)

  • Dual Channel Operation: 20A rated current per input channel with 40A peak current capability (7 seconds)

  • Advanced Monitoring: Built-in 2-channel LED DC OK indicators and relay alarm contact for system diagnostics

  • Robust Protection: Overload and short circuit protection up to 40A for 7 seconds without damage

  • Industrial Reliability: Enhanced conformal coating, 65 VDC reverse voltage protection, and Class I safety rating

  • Compact Design: DIN rail mounting with natural convection cooling

Applications: Ideal for factory automation, process control systems, building automation, transportation systems, and any industrial environment requiring high-availability power distribution with N+1 redundancy support.

 

Statement:
  1. Redundancy Modules should be considered as a part of the system components, and electromagnetic compatibility needs to be checked in conjunction with the terminal equipment.
  2. When working at an altitude of over 2000 meters, please derate 5% per KM.
  3. Installation distance: Recommended top 40mm, bottom 20mm, left and right 5mm. If adjacent devices are heating up, lateral distance of 5 mm.
  4. The case needs to be connected to ground of system when terminal equipment in operating.
  5. All indicators in this guidebook are tested according to our company's standards.
