RS-485 repeater 101-201210

PROFIBUSfiber optictransmission

1 Channel RS 485 PROFIBUS diagnostic repeater module with integrated quality-oscilloscope for 12 Mbps with diagnostic LEDs and redundancy feature. Bus connection is utilized by screw terminals and 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 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. It has on-board switchable termination and able to drive 31 devices. 1 Bus channel 31 devices/bus-loads per channel 1200 m cable length (depends on baudrate) No limit in cascading Termination switches for each channel Removable screw terminals and 1 DB9 connector Protocol Transparent for all PROFIBUS protocols 9.6 kbps .. 12 Mbps (auto detection) 2 bits delay time (12 bits in redundant mode) No address required Bus redundancy (selectable) Transmission speed detection: Auto detect (< 10 s detection and 50 s time out) Delay time (normal mode): 2.0 TBit at 9.6 kbps .. 3 Mbps; 2.75 TBit at 6 Mbps; 3.75 TBit at 12 Mbps Delay time (redundant mode): 12.0 TBit at 9.6 kbps .. 3 Mbps; 12.75 TBit at 6 Mbps; 13.75 TBit at 12 Mbps Delay time jitter: Max. ¼ Tbit Wire diameter (for the screw terminals): < 1.5 mm2 Wire type: stranded or solid core Fiber optic cable delay calculation
