2 Channel Repeater

2 Channel Repeater

2 Channel standard RS 485 PROFIBUS repeater module for 12 Mbps with diagnostic LEDs and redundancy feature. Bus connection is utilized by screw terminals and additional DB9 connector.

Request offer



The repeater channels are directly connected with the ProfiTrace OE core in the 1B/1C Head Station. Busmonitor data is directly available in the web server.

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 which are digitally filtered out. Every channel has on-board switchable termination and able to drive 31 devices.
