combined into a storage cabinet under the control of a power control unit (PCU) (Figure 3). Phoenix Contact supplies the connectors used to join these modules. For example, the polarized connectors can link modules with the 1106306 as the positive contact and the 1106307 as the negative contact. These battery pole connectors are mechanically coded to prevent accidental polarity reversal or touching, and can be rotated a full 360˚ for wiring flexibility. Conclusion Phoenix Contact offers a wide range of products intended for the All Electric Society, from connectors to sensors to control elements. It also supplies software and controllers for the automation and control of industrial systems. In addition to its products, Phoenix Contact is committed to operating sustainably by reducing CO2 emissions in its facilities and daily operations.

energy sources such as the sun and wind. The common approach is to rely on batteries for energy storage. The smallest energy storage unit is the battery cell, but multiple cells can be combined into a battery module to increase the available storage capacity. The power from the individual cells must be balanced to ensure that they are charged or discharged at a similar rate. Safety concerns require monitoring the battery module temperature to detect thermal runaway. Multiple modules are
The Phoenix Contact 2903591 is an example of a sensor module that can measure a single voltage up to 1500 volts. The output data is an analog voltage in the 2 to 10 volt DC (VDC) range, proportional to the measured input. The 2903591 sensor is a 35 millimeter (mm) DIN rail module powered by a 24 VDC source. Energy storage Since energy demand is constant, designers must be able to store generated power from renewable
