6.4.3 KROHNE RS 485 Interface (Option)

Electrical connection

RS 485 Interface (Option, connection at plug-in terminal RS)

*

The shields can be grounded as follows:

1) directly at both ends
or where there is risk of circulating currents,

2) directly at one end (static shielding) or

3) directly at one end and capacitive at the other end.

In the case of 2) and 3), a decrease in EMC is to be expected.


It is essential to blank off the final signal converter's electrical bus. To do this, solder up the
semicircular circuits of solder points S3 and S4 on the RS485 - PCB. For further information refer
to section 8.7.

The RS 485 protocol is available. Please contact your local KROHNE supplier / company.
