Product Exclusive: Smart redundancy modules have auto current balancing technology
Phoenix Contact Quint Oring active redundancy modules use new auto current balancing (ACB) technology for precise load sharing, plus load current monitoring, remote diagnostics, and visual indications, for reliable, redundant power systems.
Phoenix Contact’s Quint Oring active redundancy modules use new auto current balancing (ACB) technology for precise load sharing. The ACB technology, coupled with load current monitoring, remote diagnostics, and visual indications, ensures maximum reliability in redundant power systems. ACB automatically and symmetrically distributes the load current without regard to effects such as temperature drift. With a balanced current draw, lifetime expectancy of each power supply may double. The Quint Oring module’s display shows the status of the load sharing. If the module nears a critical state, it will generate an alarm.
In addition to the ACB, the Quint Oring module can monitor the load current. If a load powered by redundant power supplies draws more current than one power supply can provide, this essentially defeats the redundancy. At this point the Quint Oring will send an alarm to the control system. Typically this functionality would require an additional current monitoring product.
The Quint Oring can also diagnose itself. If the internal redundancy is defeated, the module generates an alarm to the control system.
Quint Oring technology uses metal-oxide semiconductor field-effect transistors (MOSFETs) for decoupling instead of the typical Schottky or silicon diode. This saves up to 70% more energy than traditional modules and reduces heat in a control cabinet.
The Quint Oring is available in two 24 V dc versions. The 32-mm-wide module accepts up to two 5- or 10-amp inputs. A 38-mm-wide version accepts up to two 10- or 20-amp inputs.
Phoenix Contact develops and manufactures industrial electrical and electronic technology products that power, protect, connect, and automate systems and equipment for a wide range of industries. Phoenix Contact GmbH and Co. KG, Blomberg, Germany, operates 47 international subsidiaries, including Phoenix Contact USA in Middletown, Pa.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
