DOLD – UH 6900 | Radio Controlled Safety Module
The DOLD UH 6900 radio-controlled safety module is a wireless safety system featuring bi-directional radio transmission – for transmitting signals between two safety modules installed on different machines. Thus, enabling one system operation. The safety module is suitable for use for equipment operated via cable.

Circuit diagrams
Radio controlled safety system UH 6900 in pair mode is for the transmission of safety inputs such as E-stop and conventional control functions and offers great flexibility for the protection of hazardous areas. The radio controlled safety system UH 6900 can be configured to easily and efficiently handle many different wireless functional safety challenges. Especially in areas where wiring would be impractical or impossible.
The Radio controlled safety system UH 6900 in group mode consisting of one group controller and up to 255 group receivers for the safety related, wireless transmission of emergency stop and control functions, offers more flexibility in safeguarding hazardous areas. High availability, long range and safety are achieved by implementing the latest radio technologies. With the group controller, several receivers can be safely switched off via a unidirectional, safety-related radio link. Furthermore, the controller can exchange message, control and status information with a receiving device.
