Product Guide

ComBricks PROFIBUS PA link/coupler module

Product description:

Introduction

The combined internal ProfiTrace and oscilloscope make this product extremely useful for remote maintenance over Ethernet. Jitter, noise, DC current, DC voltage, bar graph and oscilloscope, it is all there and easy to access. The free CommDTM allows access for asset management tools over Ethernet.

ComBricks is able to carry 9 PA links and a RS 485 or Fiber Optic module. It can also be a customized mix of PA modules with other communication modules. The PA link provides 500 mA current on a customizable bus voltage. The integrated PA termination is automatically activated when the module works as a power coupler. It is switched off in the monitoring mode.

It does not require configuration and operates the same way as regular ComBricks repeaters. In the web server the behavior on the PA side can be set, like retries (default 5) and the watchdog (default 3 seconds). This product can directly replace 3rd party Non-Ex PA couplers/links and can be used as a monitor behind existing 3rd party Non-Ex PA couplers.
