AUD
GENERAL INFORMATION
The AUD converts a oating point signal into a
linear analog output. There are two inputs on the
AUD, one to increase the analog output and one to
decrease the analog output. The output of the AUD
is stable when the inputs are both o . A contact
closure or voltage signal to either input will cause
the output of the AUD to begin to ramp either up or
down depending on which input was activated.
The output stops ramping once the up or down
input is deactivated, and will remain at that value
until another up or down signal is received. If both
inputs are "ON," the output will reset to the lowest
value of the selected range.
is in the form of an analog, steady state voltage or
current. This signal can be scaled to t the needs of the
application by selecting one of several preset ranges
by dip switch or by adjusting the o set and the gain of
the output with two potentiometers.
MOUNTING INSTRUCTIONS
Circuit board may be mounted in any position. If circuit board slides out of snap track, a non-conductive
"stop" may be required. Use only ngers to remove board from snap track. Slide out of snap track or push
against side of snap track and lift that side of the circuit board to remove. Do not ex board or use tools.
WIRING INSTRUCTIONS
PRECAUTIONS
• Remove power before wiring. Never connect or disconnect wiring with power applied.
• When using a shielded cable, ground the shield only at the controller end. Grounding both
ends can cause a ground loop.
• It is recommended you use an isolated UL-listed class 2 transformer when powering the unit
with 24 VAC. Failure to wire the devices with the correct polarity when sharing transformers may
result in damage to any device powered by the shared transformer.
• If the 24 VDC or 24VAC power is shared with devices that have coils such as relays, solenoids, or
other inductors, each coil must have an MOV, DC/AC Transorb, Transient Voltage Suppressor (ACI
Part: 142583), or diode placed across the coil or inductor. The cathode, or banded side of the DC
Transorb or diode, connects to the positive side of the power supply. Without these snubbers,
coils produce very large voltage spikes when de-energizing that can cause malfunction or
destruction of electronic circuits.
• All wiring must comply with all local and National Electric Codes.
