EtherNet/IP IO-Link master block for welding environments

Industry 4.0 overview
Industry 4.0 overview

Simplify smart service integration in harsh industrial environments

Electromagnetic interference (EMI) can negatively impact work processes, interfering with digital, analog and communication equipment. Balluff's new IO-Link master can insulate your productivity by:

  • Reducing inductive noise with coil choke filters.
  • Reducing conductive noise with its fiberglass-reinforced plastic, polypropylene sulfide (PPS) housing, that breaks conductive loops.
  • Reducing capacitive noise by raising the PCB further from the backplane. Since PPS is non-conductive, the housing does the work of a separate grounding plate.

PPS is also inherently non-stick, so welding spatter slides off it.

This block offers four Class A IO-Link ports and four Class B IO-Link ports. The Class A ports can be connected to 3- or 4-pin IO-Link devices using appropriate cables. Pin 2 can be used for an actuator power on these ports and it is powered through the device power (Us). Pin 2 on these ports can be used as a digital in/out. Class B ports are primarily used for devices requiring isolated actuator power (Ua), for example in robotic grippers or valve manifolds, and are connected using 5-pole cables. The 3-pin Class A devices can also be connected to the Class B master port on this master using a 3-pole cable.

Like other Balluff IO-Link master blocks, the BNI00CY offers advanced features. Its built-in display allows configuring of network parameters and aids during troubleshooting. Connect to its embedded web server to remotely configure the block and connected IO-Link devices. In difficult EMI and welding environments, this block keeps performing.
