4.9.2830-2 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.
