Description
The APD 7580 accepts a frequency input and provides an
optically isolated DC voltage or current output that is linearly
related to the input.
Common applications include frequency to DC conversions
from frequency output type devices such as rotary encoders,
magnetic pick-ups, proximity sensors, variable speed drives,
and flow meters. For PLCs that do not have analog outputs,
often the pulse rate of a discreet output can be programmed to
vary. By connecting the APD 7580 to this output, a proportional
analog signal can be generated. A 15 VDC power supply is
provided to power the sensor input, if required.
Full 3-way isolation (input, output, power) makes this module
useful for ground loop elimination, common mode signal rejec-
tion or noise pickup reduction.
The APD 7580 input and output can be field-configured via
external rotary and slide switches. Common ranges are on
the module label. Many additional combinations are possible.
Consult the factory for assistance with special ranges.
Sink/Source Versatility
For maximum versatility the output can be selectively wired for
sinking (unpowered) or sourcing (powered) milliamp output.
The 20 VDC loop excitation supply can be used to power a mil-
liamp current loop if required. The output can also be wired for
an externally powered loop.
LoopTracker
API exclusive features include two LoopTracker LEDs (green for
input, red for output) that vary in intensity with changes in the
process input and output signals. These provide a quick visual
picture of your process loop at all times and can greatly aid in
saving time during initial startup and/or troubleshooting.
Output Test
An API exclusive feature includes the test button to provide a
fixed output (independent of the input) when held depressed.
The test output level is potentiometer adjustable from 0 to
100% of output span.
The output test button greatly aids in saving time during initial
startup and/or troubleshooting.
