Product description

The Wireless E-Stop-System includes a very compact and ergonomic remote control RE 5910 and a safety module with radio control BI 5910. The remote control provides personal protection when entering dangerous areas and allows besides the emergency stop function also control functions with the integrated push buttons and switches. The safety outputs of the BI 5910 guarantee safe disconnection. For control functions it includes 7 semiconductor outputs.

  • Ideal solutions for mobile and stationary machines and plants with dangerous areas
    - During automatic operation e. g. to clear failures
    - During set up e. g. to adjust machine parameters, maintenance, set up
  • Higher availability of machines because damage of trailing cables is avoided
  • Less mounting, installation and wiring time
  • No wearing on trailing cables, slip rings etc.
  • Easy retrofit and modernising of machines
  • Optimised sight on operating area during set up
  • User legitimating with electronic key on remote control possible
