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.
