Commissioning↑
The Relay 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. For loads exceeding 12A, use a wire cross-section of 2.5mm².
|
For thermal reasons the total load rating must not exceed 48A (IEC) or 45A (UL). |
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.

Diagnostic Inputs↑
| Summary | Description | Unit | Value Range |
|---|---|---|---|
| Online Status Relay Extension | Indicates whether the device can be reached by the Miniserver. Diagnostics for Air devices Diagnostics for Tree devices Diagnostics for Extensions |
Digital | 0/1 |
| System temperature | Provides the internal device temperature. This is often the temperature of the CPU or another location in the device. |
° | ∞ |
| Temperature Shutdown | If the CPU temperature reaches a critical point, the outputs of the device are switched off. This can be due to short-circuits, overloaded switching loads or too high an ambient temperature. | Digital | 0/1 |
Properties↑
| Summary | Description | Default Value |
|---|---|---|
| Serial Number | Specifies the serial number of the device. For Extensions: Enter 'Auto' to automatically pair an extension with unknown serial number. This can only be used if there is only one Extension of the same type. Save into the Miniserver, in order to pair the Extension. Afterwards the program must be loaded from the Miniserver to transfer the actual serial number of the Extension into the program. |
