Wiring the Serial DAC
The Serial DAC provides a robust analog output sig-
nal. The module converts the proprietary Serial DAC
signal from the controller’s open collector output in
conjunction with the clock signal to an analog current
or voltage. See Figure 2 for wiring a Serial DAC. The
Serial DAC is user-configurable for voltage or current
output. Refer to Figure 3 for configuration information.
The Serial DAC optically isolates the controller’s con-
trol output from the load. One Serial DAC may be
powered by the 5V
Î (dc) supplied by a CLS200,
MLS300 or CPC400 controller at its output terminal
board. These controllers cannot provide sufficient cur-
rent for more than one Serial DAC; use an external
power supply.
Figure 2. Single or Multiple Serial DACs with External
Power
Configuring Serial DAC Outputs
The Serial DAC’s voltage and current output is jumper
selectable. Refer to Figure 3. Configure the jumpers as
indicated on the Serial DAC label.

WARNINGS
Ó
WARNING
The SDAC module is for indoor use only. To reduce
the risk of fire or electrical shock, install in a con-
trolled environment relatively free of contaminants.
Ó
WARNING
Use a power supply with a Class 2 rating only.
NOTE
Tighten screw terminal connections to 0.5 to 0.6 Nm
(4.5 to 5.4 inch-pound).
NOTE
Use copper conductors only.
