    ORING modules with ACB technology provide the best possible protection for power supply units – for superior system availability.

  • Diode modules
    Diode modules

    Diode modules decouple power supplies that are operated in parallel: a short circuit no longer affects the load.

A safe redundant system helps to ensure higher system availability and productivity. This is the result of the parallel connection of two power supply units which are disconnected from each other. To further increase the system availability, additional monitoring of the redundancy is recommended. That's why decoupling with an active redundancy module is an ideal solution, as the module also monitors and controls, as well as providing easy decoupling with diodes.

Your advantages

  • Corresponding functionality and design, tailored to power supplies from Phoenix Contact
  • Consistent redundancy up to the load, thanks to two positive output terminal blocks per module
  • Service life is doubled – ORING modules with ACB technology ensure symmetrical utilization
  • Save 70% energy: ORING modules decouple with MOSFETs instead of diodes

QUINT ORING active redundancy module – decoupling, monitoring, and controlling

Decoupling, monitoring, and controlling with an active redundancy module  

Decoupling, monitoring, and controlling with QUINT ORING

The QUINT ORING active redundancy modules monitor the entire redundant solution, i.e., the power supply unit voltages, the wiring, decoupling, and the load current. Critical operating states can therefore be detected at an early stage and redundancy can be restored.

Decoupling with diode

Decoupling with diode  

Decoupling with the QUINT, TRIO, UNO or STEP diode

If the power supply units are decoupled, a short circuit at the output of one of the power supply units or in the supply line from the power supply unit to the diode no longer has any effect on the load.
