20 A redundancy (decoupling) module for 24 VDC power system. Containing 2 sets of 20 A Or-ing diodes with wonderful heat dissipation deployment, DR-RDN20 gives you a new option for safe connection of a 1+1 redundant supply set-up. Not only perfectly decoupling power sources from each other but also from the load, DR-RDN-20 also provides users monitoring signals for both input channels through the built-in relays. Since there's no switching components inside the module, DR-RDN-20 will not generate additional EMI issues and should provide you a worry-free application platform.
