VTI Instruments Corp., Irvine, CA, has released the EX1200-1538 multifunction I/O card that delivers eight channels of independent 1-MHz frequency/32-bit counter inputs, 16 channels of isolated digital I/O, and two channels of isolated analog output (DAC) in a single instrument. The instrument is suited for electronic functional test (ATE) and data acquisition (DAQ) applications, including precision frequency and counter/timer measurements in ATE systems, motion or position measurements from rotating shafts, and monitoring the speed of motors or turbines. It is used in industrial control applications such as relay actuation, speed control, and simulation requiring protection against high common mode and transient voltages. Time and frequency domain measurement accuracy is obtained with electronic counter implementation. The instrument can directly measure frequency, totalize counts, RPM, and quadrature input signals. The isolated digital I/O and DAC output channels provide the ability to directly measure and control a range of industrial systems, and can be combined to achieve expanded voltage and current levels.
