Unit for galvanic isolation of P-NET RS485 signals

Specific Features

This boxed unit contains some optically linked modules from the PD 600 series, to provide galvanic isolation between two parts of a single P-NET segment.

· The unit can be useful within installations where P-NET needs to be connected between two or more buildings, for providing the necessary galvanic isolation.  

· By adding this high level of galvanic isolation, it can also help to minimize damage caused if an installation is struck by lightning.

Block Schematic

Installation:

Please note that the shield should not be connected to CHASSIS as described in the P-NET Installation Guide, since the enclosure and the DIN rail are made of plastic.

To avoid the 'S' reference potential floating free, the shield should be connected to ground. This could, for example, be done by the use of a third wire in the cable used for the 24 V DC power supply.
