Kevin's Notebook: The Fine Art of Analog Signal Sampling
The fine art of converting a continuous analog signal into synthesized discrete digital information (a mouthful for A/D conversion) involves two important accuracy considerations. It also reflects the characteristics of the sampled analog signal. These two considerations involve breaking down the analog signal’s magnitude into discrete levels or steps (quantization) and setting the data sampling rate based on the signal’s maximum change frequency component (aliasing and the Nyquist Frequency). Read the rest of the story.

Data acquisition monitor and control equipment
Driven by the need for continuous improvement in manufacturing floor and
machine efficiencies, demand for quality, real-time data acquisition systems
has increased steadily. With the increased factory floor utilization of
LAN-based systems with Ethernet or emerging wireless technologies,
the capability of monitoring, reporting, and control of embedded
machine-level sensors has become a possibility.
As monitoring becomes more common-place, digital data acquisition and
Ethernet and wireless communications systems will be directly incorporated
within machines. However, before the future becomes reality, connecting
these advanced systems to legacy equipment with generic I/O or
RS-232/RS-485 outputs will require cost-effective analog-to-digital
media converters.
B&B Electronics offers a broad portfolio of data acquisition modules,
buffers, extenders, analog and serial I/O converters to meet the data
conversion requirements of the efficient factory floor revolution.

Advantech ADAM 4000 & 6000 series remote data acquisition and control systems
The ADAM series modules are compact, versatile sensor-to-computer
interface units designed specifically for reliable operation in harsh environments.
Their built-in microprocessors, encased in rugged industrial grade plastic,
independently provide intelligent signal conditioning, analog I/O and digital
I/O via RS-485 serial or Ethernet communications.
Remotely programmable input ranges
The ADAM series modules stand out because of their ability to accommodate multiple
types and ranges of input. The type and range can be remotely selected by issuing
commands from a host computer. One type of module satisfies many different tasks,
which greatly simplifies design and maintenance. A single kind of module can
handle the measurement needs of a whole plant. Since all the modules are remotely
configured by the host computer, physical adjustments are unnecessary.
Watchdog timer inside
A watchdog timer supervisory function will automatically reset the ADAM series
modules if required, which reduces the need for maintenance.
Modular industrial design
The ADAM series modules offer flexible mounting options, including DIN rail
mounting, panel mounting or piggybacking. Signal connections are made through
plug-in screw terminal blocks, ensuring simple installation, modification and
maintenance.
Ready for the industrial environment
The ADAM series modules accept any unregulated power source between 10 and
30 VDC. They are protected from accidental power supply reversals and can be
safely connected or disconnected without disturbing a running network. |
Distributed I/O over RS-485
Digital input/output modules over RS-485
The ADAM-4000 series modules use the RS-485 communication protocol, the industry's most widely used bi-directional, balanced transmission line standard. It lets the ADAM-4000 series modules transmit and receive data at high rates over long distances Common Features - Built specifically for harsh environments
- DIN rail, panel and piggy back mountable
- Built-in microprocessor
- 10 to 30 VDC power input
- Built-in watchdog timer
- MODBUS support on most models
