The Model 2147 Bit-Driver used in a PROFIBUS-DP application is a two fiber optic port repeater
with single TIA/EIA-485-A electrical port. The 2147 operates at rate 9600 baud to 12 Mbaud in linear bus topology.
The 2147 can be used as an optical repeater between the fiber optic segments, an optical to electrical converter
between a fiber optic segment and electrical station(s), or T-connector/repeater between two fiber optic segments and electrical station(s). The 2147 is transparent and does
not evaluate the PROFIBUS data exchange. Model 2147 can be configured to operate in redundant ring topology.
Using fiber optics over the physical layer, the 2147 provides longer segment distances, electromagnetic noise immunity,
and ground potential difference independence in the linear bus topology. The 2147 can be optionally equipped with
optics of different characteristics.
The 2147 retimes the received optical signal and can link up to 32 fiber optic segments in series. The electrical
port supports up to 31 stations.
The 2147 Termination switch can select an internal cable type-A termination. External terminations
can derive power from the sub-D connector between pins 6 and 5.
The 2147 unit attaches to EN50022 (35mm DIN) mounting rail. Redundant power is applied through
screw terminals and data rate selection made automatically with visual indicator of speed display.
UL Listed. Meets FCC requirements of Class A, Part 15 Computing Devices Standard.
