Auto Current Balancing, Smart Redundancy Modules from Phoenix Contact
Middletown, PA — Phoenix Contact’s Quint ORing active redundancy mod- ules use new auto current balancing (ACB) technology for precise load sharing. The ACB technology, cou- pled with load current monitoring, remote diagnostics and visual indica- tions, ensures maximum reliability in redundant power systems. ACB technology 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 criti- cal state, it will generate an alarm. In addition to the ACB, the
module can monitor the load current. If a load powered by redundant power supplies draws more current than a single power supply can pro- vide, this essentially defeats the redundancy. At this point the Quint ORing will send an alarm to the con- trol system. Typically this function- ality would require an additional current monitoring product. The Quint ORing can also diag-
nose itself. If the internal redundan- cy is defeated, the module generates an alarm to the control system.
Quint ORing technology uses MOSFETs for decoupling instead of the typical Schottky or silicon diode. This saves up to 70 percent more energy than traditional modules and reduces heat in a control cabinet. The Quint ORing is available in
two 24VDC versions. The 32mm- wide module accepts up to two 5- or 10-amp inputs. A 38mm-wide version accepts up to two 10- or 20-amp inputs. Both are approved for use in
Class I, Div. 2 hazardous locations. Contact: Phoenix Contact, Inc.,

The light from high-output
LEDS in 4 quadrants each with 8 step variable intensity from 0 to 100 percent is refracted through an inno- vative optical system to provide 85,000 lx at a working distance of 3- in. (76mm). The 4 quadrant zones can be
individually turned on and off, which can eliminate shadow for smooth, even illumination or conversely, cre- ate and control shadows to define surface details. The RL16Q and RL28Q with Quadrant Driver comply with CE standards for European
