5.2.6 Analog Outputs (Channels AO1–AO4)

Voltage in the range of 0–10 VDC (with up to 4 mA of current) can be outputted by

assigning analog outputs. Configure an output using a web browser. For DC

voltage, the output voltage is applied to point A with respect to C (common).

Any channel AO1–AO4 can be used to provide an analog voltage output. The

BACnet type will be Analog Output. To configure an analog output:

 On the Main Page (Figure 13), click a title link from among AO1–AO4.

 Under BAS Channel Configuration (lower) section of the new screen that

appears (Figure 24), the Channel Type will be Analog Output (read-only).

 In the BACnet Object Configuration (lower) section of the screen, all items

are as described in Section 5.2 above — but Units defaults to VOLTS.

 Attach your device to the pair of BASC20 pins for the chosen channel — so

that the more positive connection is to pin A and the more negative to pin C.
