ComBricks PROFIBUS PA coupler module

pa moduleThe PROFIBUS PA segment coupler module enables seamless integration to PROFIBUS PA. The coupler powers the attached devices and forwards telegrams coming from the backplane. The combined internal ProfiTrace and oscilloscope make this product extremely powerful for remote maintenance over Ethernet and the use of asset management tools.

The PA segment coupler does not require configuration and operates the same way as regular ComBricks repeaters. The coupler has advantages compared to other existing couplers:

• Transparent on 9.6 kbps up to 1.5 Mbps.
• Customizable PA voltage.
• Can directly replace 3rd party Non-Ex PA couplers.
• PA monitor behind existing 3rd party Non-Ex PA couplers.
• Very small dimensions.

The backplane can handle 10 PA coupler modules or a mix of PA modules with other communication modules.

The integrated PA termination is automatically activated when the module works as a regular PA coupler. It is switched off in the monitoring mode.
