DR-RDN20 - Din Rail Instal Redundant Module
Home > Products > Din Rail Instal Redundant Module
Features- Suitable for redundant operation of 24V system
- Installed on DIN Rail TS35 / 7.5 or 15
- Relay contact signal output and LED indicator for input failure alarm
- Cooling by free air convection
Description20A redundancy (decoupling) module for 24Vdc power system. Containing 2 sets of 20A Or-ing diodes with wonderful heat dissipation deployment, DR-RDN20 gives you a new option for safe connection of 1+1 redundant 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.
