4.6 Analog Outputs
Voltage in the range of 0 –10 VDC can be outputted by assigning analog outputs
(AO1–AO4). For analog output DC voltage, the output voltage is applied to point A
with respect to C (common). There is no configuration necessary for analog outputs.
Figure 8 illustrates connections to a three-wire damper actuator. The damper
requires a 0
–10 V command signal which can easily be accomplished by the
BASC20. If position feedback is to be measured, connect the actuator output signal
to UI1 and configure the universal input for analog input.
