Abstract

This paper describes about an alternative module of data acquisition system (DAS), which can be accessed by LabVIEW. The advantage of this DAS module is inexpensive and it has good performance as well as module used in industrial control system. This DAS module is controlled by ATmega64 AVR microcontroller, which will communicate with the LabVIEW by using bidirectional serial communication. This DAS module has 8-bit digital input, 8-bit digital output, 8 channel analog inputs, 2 channel analog outputs. Voltage levels of digital input are 0 – 5 V and 0 – 24 V. The digital output of this module is an open collector terminal with “low” level voltage of 0.276 V. Analog input of this DAS module has three ranges. They are 1 – 5 V with average error of 14.47 mV, 0 – 10 V with average error of 72.34 mV, and 4 – 20 mA with average error of 0.037 mA. Range of analog output of this module is 0 – 10 V with average error of 16.2 mV. This DAS module is not designed for applications that need high accuracy of time.
