Analog Output

Either voltage in the range of 0–10 VDC or current in the range of 0–20
mA can be outputted by assigning analog outputs. Configure an output
using a web page. Select the appropriate range. For DC voltage, the
output voltage is applied to point A with respect to common. For DC
current, the output current is sourced from point A to common so there
is no need for a loop supply. A current output can source up to 20 mA
into a resistive load not exceeding 750 Ω. Verify the burden that a
current output device will present. The BAS Remote can not generate
enough voltage to drive loads with higher resistance.

Figure 15 — Analog Output Connections

Figure 15 illustrates connections to a three-wire damper actuator. The
damper requires a 0–10 V command signal which can easily be
accomplished by the BAS Remote. However, if a current output is
desired it is possible to set the BAS Remote analog output to 4–20 mA
and install an external 500 Ω resistor that will convert the 4–20 mA
signal to 2–10 V.
