4.9.2 830-2 Connecting Cable

Uses

The 830-2 connecting cable is a preassembled cable for fast and cost-effective

attachment of PROFIBUS nodes (for example HMI) to programmable controllers

for transmission rates up to 12 Mbps.

Design

The 830-2 connecting cable consists of the PROFIBUS standard cable. It has a

9-pin sub-D male connector with a straight cable outlet at one end and a 9-pin

sub-D male connector with a 90° cable outlet at the other. The connector with the

90° cable outlet is equipped with a PG interface. The terminating resistors can be

activated in both connectors. The cable is available in lengths of 3 m, 5 m and

10m.
