Functional description LD-63 Profibus

LD-63 Profibus is a line splitter for use in multi-drop fibre optic networks. The LD-63
Profibus allows conversion between RS-485 and fibre optic. The unit is specially
developed for Profibus and uses a Profibus standard 9-position D-sub for connection
with RS-485. Possibility to connect to a 5-position screw block is also available.

The fibre optic interface uses ST-connectors and both multi mode and single mode fibre
versions are available. The maximum transmission distance is calculated from the available
power budget of the modems and the attenuation of the cable, splice joints and connec­tors. Distances up to 25 km can be reached using single mode fibres.

The modem consists of two F/O channels, each with its separate transmitter and receiver
(TX1, TX2, RX1 and RX2). On the front of the unit there are seven LED’s indicating the
datatransmission on the channels.

LD-63 Profibus can be used at all standard Profibus transmission speeds up to 1.5 Mbit/s
and all operating parameters are set-up via DIP switches easily assessable under the lid on
the top of each unit.

LD-63 Profibus is available in low (LV) and highvoltage (HV) versions. LD-63LV supports
power supplies 12–45V AC ± 5% and 12–55V DC ± 5%. LD-64HV supports power supp­plies 95–240V AC ± 5% and 110–240V DC ± 5%.
