Introduction

The RS 485-IS barrier is the only available product for remotely monitoring IS segments over Ethernet from the safe zone. Because of the permanent mounting of the barrier, the user does not have to touch the installation anymore. This avoids hot permits and other paper work.

As an alternative it can also be used as a busmonitor on existing IS segments created by 3rd party barriers. The IS barrier can be mixed on the backplane with other ComBricks modules like, the PROFIBUS PA, Fiber Optic and regular RS 485 modules.

The Barrier is intended to be installed outside the hazardous area or in an enclosure with a suitable type of protection. A special IS DB9 PROFIBUS plug is required that contains a terminator defined in the RS 485-IS PROFIBUS Installation Guideline.
