2.3 Modbus Cables and T-parts
2.3.1 RJ45 FTP cables
For connecting instruments to Modbus you need shielded cables with at least 3 wires (for data only). Recommended
are twisted wire cables for RS485-communications with 100 or 120 Ohm impedance. All Bronkhorst Modbus cables
have also integrated power-supply wires. For the use in the EL-FLOW range (non IP-65) it is best to use Shielded
(+Foiled) Twisted Pair patch-cables with RJ45 modular jack connectors (8-pins for data and power-supply
connections).
