GWY-CB-1-BR-IO-165049 (Order no. 165049)

IO-Link Gateway for BP/BR switches

  • IO-Link device for reading process and device data of BP/BR safety switches and transferring them to a higher-level control system
  • Control of guard locking of BP/BR switches, depending on the switch used
  • Compact version measuring only 12.5 mm in width
  • Rail mounting
  • LED status indicators
GWY-CB-1-BR-IO-165049 (Order no. 165049)


Industry 4.0 ready

Process data are cyclically sent to the control system via IO-Link. These data include all status signals, such as the door or guard locking position, and the indication of whether a switch is in the limit range of the actuating range.

The process data are available to the control system after approx. 200 ms and can be used for the automation process.

Plug and Play series connection

  • Connection for safety switches with BR technology without addressing the individual switches
  • The wiring and configuration work is minimized.

Device data and events

The higher-level control system can poll more than 30 different items of information from the connected switches. Comprehensive data transmission via IO-Link enables targeted preventive maintenance, for example.

Simple implementation of innovative applications

Device data from the actuators used can be employed to detect individual rotary table positions or different containers, for example.
