Is it time to go On-machine? The "On-machine" philosophy moves automation and safety controllers on to the machine itself, rather than in a centrally-located cabinet, resulting in time and space savings. Read how this philosophy has been implemented in various industries.

The ArmorStart Virtual Demo explains the benefits of the ArmorStart® Distributed Motor Controller family, including:

  • Product positioning within the product family
  • Potential savings when using the On-Machine solution
  • DeviceNet™ and EtherNet/IP™ network solutions
