Our Bulletin 1485 Auxiliary Power Media connection devices are based on a 4–pin connector system and is used to provide 24V DC power to I/O modules and other devices separately from network power. Running separate power to these devices is typically used for I/O devices with output connections to prevent power supply interruption due to switching of outputs. However, some devices require separate auxiliary power to power them regardless of the presence of outputs.

Overview

  • Can provide power through only one pair of the four available contacts, so the other available pair can be used for single channel E-stop
  • E-stop T-ports and shorting plugs are red for easy identification
  • Many end devices, including Rockwell Automation® hardened I/O products, use a different pin numbering convention for 4-pin mini connections than that used on physical media products
  • Both conventions have the same color code going to the same spot but they use a different pin numbering designation
