Radio controlled safety system Group mode

SAFEMASTER W - Wireless Safety
Wireless Functional Safety in group mode

The radio controlled safety system UH 6900 of the SAFEMASTER W series comprising a group controller and up to 255 group receivers for the safety transmission of emergency-stop and control functions provides more flexibility when securing dangerous areas. The group controller can be used to let several receivers securely shut down through a unidirectional, safety radio transmission. Furthermore, the controller together with a receiver can exchange indicator, control and status information. The main application areas include mobile applications, such as completely-automated floor conveyors and automated guided vehicles.

  • For safety applications up to Cat. 4 / PL e or SIL CL 3
  • High availability with long transmission range
  • Two-channel safety inputs and outputs (Group receiver)
  • Control inputs and outputs
  • Quick Start, fast set-up procedure
  • Convenient diagnostic options
