VISY-ICI 485

Introduction
The VISY-ICI 485 is a communications adapter to connect VISY-Input 8 and VISY-Out-
put 4 components to the VISY-Command.
The connection is established by an RS-485 interface. The interface is galvanically isolated
from the rest of the circuit, and therefore from the VI-… interface card, by optocouplers
and a DC/DC converter. Galvanic isolation improves the reliability of the communication.
For a convenient integration into VISY-Command, the printed circuit board (PCB) of the
VISY-ICI 485 is mounted on a module carrier for subsequent installation on DIN rails.

•
Modifications to the VISY-ICI 485 are prohibited without the prior consent of the
manufacturer.
•
The installation and configuration of the VISY-ICI 485 communications adapter
must be carried out only by expert, authorised personnel. Specialised knowledge
must be obtained by regular training.
•
Operators, installers and service technicians must comply with all applicable safety
