Table of Contents


The AI Extension is installed on a DIN rail in a suitable enclosure.

Connect the power supply and Link communication to the Miniserver.

Connect devices that provide a 0-10V signal to the analogue inputs, e.g. 0-10V temperature sensors. When using the inputs as digital inputs, 24VDC can be connected to the inputs via retractive switches for example.

If the devices are connected to different power supplies, it is essential that the GNDs are interconnected.

The Extension starts after switching on the power supply, and the status LED will flash orange after a short time when the connection to the Miniserver is established.

Then follow the pairing procedure on the Link Interface.
