New Distributed Data Acquisition System Debuts

With a topology that uses a controller board plugged into a computer and external A/D boxes for direct connection to thermocouple, RTD, voltage, thermistor, bridge and strain sensors, InstruNet Series is a high-accuracy distributed data acquisition system for Windows 95/NT and Macintosh computers. Each external A/D box has 16 single-ended and 8 differential analog inputs, 8 analog outputs and 8 digital I/O. Each controller card in the computer can connect up to 16 external A/D boxes that can be placed on a network up to 1000 feet away from the computer for a total of 256 analog inputs, 128 analog outputs, and 128 digital I/O. Each channel has independently programmable analog filters. System includes software and numerous drivers.
