For use in Zone 2 explosion risk areas, a Quint Diode redundancy module allows power supplies connected in parallel to provide redundancy can now be fully decoupled.
For use in safe areas and those with a Zone 2 explosion risk, Phoenix Contact is now offering the Quint Diode redundancy module compliant with type 'n' explosion protection as defined by EN 50 021. This means that power supplies connected in parallel to provide redundancy can now be fully decoupled. The use of power supplies with high operational reliability increases the availability of the overall system.

Redundant systems also minimise downtime, with 2 power supplies connected in parallel each dimensioned so that the overall power requirement of all consumers can be covered by a single device.

If the system availability is to be increased even further, the logical solution is to use a diode redundancy module.

Then even if a short circuit were to occur at the output of one of the power supplies, the second automatically takes over the task of supplying the consumers, thus ensuring an uninterrupted power supply.

The din rail mounted module is fast to install, handles currents up to 60A and operates in ambient temperatures in the Ex areas of -25 to +60 deg C.

Phoenix Contact is one of the world leaders in developing and manufacturing connectivity solutions and automation components.

Its principal product ranges include: printed circuit board connectors; modular terminal blocks; fieldbus components; surge voltage protection systems; industrial plug and socket connectors and interface units.
