PBMX IP67 (Set ) | PROFIBUS Active Measuring Point 110080005

Active measuring point PBMX IP67 (Set)

For the purpose of physical determination of the signal-to-noise ratio of the PROFIBUS communication, feedback-free measuring points are required in every segment of a master system. To get optimal information on the physical transfer quality, the measuring points have to be provided at both ends of a segment.

The PBMX with the protective system IP 67 can be used without protective casing in a rough production environment. The PBMX meets not only the requirements of a feedback-free measuring point but also fulfills the requirements and the function respectively of an active bus termination.

The 24V connection ensures the 5 V voltage supply for the terminating resistor according to an internal DC/DC transformer.

The diagnostic tools are connected according to the free M12 measuring socket.

The PBMX-Set includes (ready-to-install items):

• 1 x active measuring adapter PBMX (bus termination)
• 1 x power cable M12 (female), standard length 3 m
• 1 x unilaterally converted PROFIBUS cable (female) 2 m
