Two new models have been added to Tidal Engineering's ADAIO family of precision analog I/O expansion solutions for embedded applications. These compact and versatile microcontroller-based devices provide both analog input and output, and employ the I ² C Bus. The TE1313 and TE1243 modules provide one digital-to-analog output channel with resolutions of 16 bits and 12 bits respectively, and one 16-bit bipolar/unipolar analog-to-digital input channel with an input range from 0.1 to ±10 V DC. Providing industrial I/O with modular flexibility, the devices are 2.87" (L) × 0.75" (W) × 0.7" (H). The units are specifically engineered to mount directly to Tidal's full line of embedded IEEE 488 single board computers, enhancing their I/O capability. The modules are equally suitable as stand-alone devices in a wide range of data acquisition and measurement applications, including signal measurement and process control. Prices start at $150.00 each for the TE1243 and $180 each for the TE1313. Delivery is from stock to six weeks.
