Randolph, NJ — Two new
modules have been added to Tidal Engineering's ADAIO family of precision
analog I/O expansion solutions for embedded applications. These compact,
versatile microcontroller-based devices are said to provide both analog input
and output, and use the I2C Bus.
According to the vendor,
both modules provide one digital-to-analog output channel with resolutions of
16 and 12 bits respectively, and one 16-bit bipolar/unipolar analog-to-digital
input channel with an input range from 0.1 to ±10VDC.
Providing industrial I/O
with modular flexibility, these devices are housed in a 2.87 x 0.75 x 0.7-in.
space-saving design. The units are specifically engineered to mount directly
to the company's full line of embedded IEEE-488 single-board computers,
enhancing their I/O capability.
Commonly used with the
vendor's SBC448A to provide a flexible instrument development platform, the
modules are equally suitable as standalone devices in a wide range of data
acquisition and measurement applications including signal measurement and
process control.
These new devices provide
optically isolated data, with up to 1000V of optical isolation, and an onboard
DC/DC converter to eliminate the need for a second isolated power source.
Their DAC Full Scale (FS) output range is selectable for 1.0V FS, 5.0V FS and
10.0VDC, while the units' microcontrollers provide median filtering for the
ADC. Conversion time is stated at just 4 milliseconds. Modules' operating
temperature range is 0° to 50°C, and power requirement is 5VDC at 50mA. The
company also offers ADAIO modules with 12-bit DACs as well as a wide range of
analog-to-digital converters.
