Extension

The Extension features 8 potential free relay outputs, 12 digital inputs, 4 analogue 0-10V inputs and 4 analogue 0-10V outputs.

The digital inputs can also be used as frequency counters, to connect for example S0 meters or wind sensors that transmit pulses.

The analogue inputs can also be used as digital inputs.

Commissioning

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

Connect the power supply and Link communication to the Miniserver.

Connect the loads to the relay terminals. You will find various connection examples below.

Many electronic loads such as ballasts, power supplies, LED drivers and high voltage LED lamps can draw high inrush currents of over 20A. Use inrush current limiters or a coupling relay with the necessary current rating for such cases.

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
