Diode modules

Fully redundant

Easy decoupling of power supplies that are operated in parallel ensures a high level of availability.

  • Product list QUINT DIODE

    QUINT DIODE diode modules feature full redundancy up to the consumer and increase system availability even under demanding ambient conditions.

  • Product list TRIO DIODE

    TRIO DIODE redundancy modules permanently monitor redundancy from the output voltage to the redundancy module.

  • Product list STEP / UNO DIODE

    STEP / UNO DIODE narrow diode modules decouple power supply units that are connected in parallel and provide 100% redundancy.

Diode modules decouple parallel-switched power supplies. This means that a short circuit no longer
affects the load. Whether at the output of one of the power supply units or in the supply line from the power supply unit to the diode -
diode modules ensure absolute supply reliability from the power supply.

Your advantages

  • QUINT DIODE – Consistent redundancy, thanks to redundant wiring through to the load, with two positive output terminals
  • Robust design – QUINT DIODE for potentially explosive areas and demanding ambient conditions
  • Wiring is checked: TRIO DIODE monitors the wiring from the power supply to the diode
  • TRIO DIODE with Push-in connection for fast and easy installation
  • Space saving on the DIN rail, because the STEP DIODE is just 18 mm wide
  • Diode modules are part of the COMPLETE line system

TRIO DIODE - redundancy modules for decoupling and monitoring

TRIO DIODE for decoupling and monitoring  

Decoupling and monitoring with TRIO DIODE

The TRIO DIODE redundancy modules check the output voltage of the power supplies and the wiring up to the decoupling module.

Furthermore, they also indicate voltage dips via the floating relay contact and “Redundancy OK” LED.


TRIO DIODE – Redundancy modules with Push-in connection

TRIO DIODE with Push-in connection  

Quick and easy installation, thanks to Push-in connection technology

Thanks to Push-in connection technology, the diodes in the TRIO range can be quickly and easily installed. In this way, you can increase system availability.

UNO, STEP, and QUINT DIODE – Redundancy modules for easy decoupling

UNO. STEP and QUINT DIODES for decoupling  

Diode modules for nominal voltages from 5 to 48 V DC

UNO DIODE, STEP DIODE, and QUINT DIODE are the ideal choice when it comes to easy decoupling of power supplies.

A short circuit in the power supply unit output circuit or the supply lines to the diode module no longer affects the load. The system continues to be reliably supplied with power.

QUINT DIODE – Redundancy modules for demanding ambient conditions

QUINT DIODE for demanding ambient conditions  

High system availability due to robust design

Thanks to their robust design, the QUINT family diodes ensure high system availability even in potentially explosive areas and demanding ambient conditions. Use the module for redundancy or to increase performance.
