1 Channel RS 485 PROFIBUS diagnostic repeater module

1 Channel RS 485 PROFIBUS diagnostic repeater module with integrated quality-oscilloscope for 12 Mbps with diagnostic LEDs and redundancy feature. Bus connection is utilised by screw terminals and an additional DB9 connector.

The repeater channel and the integrated oscilloscope are directly connected with the ProfiTrace OE core in the 1B/1C Head Station. Scope images and busmonitor data are directly available on the webserver.

The advanced 12 Mbps core of the repeater module can be cascaded unlimitedly and has increased RS 485 strength. The data traffic is constantly monitored for glitches that are digitally filtered out. It has on-board switchable termination and able to drive 31 devices.
