MULTI-IO 31

This module is used to acquire analog signals from any transducer after suitable signal conditioning, or from any analog source. The analogue input must be in the range of 0V to 5V DC. 8 independent analog inputs or 16 common ground analog inputs can be connected to this module. These analogue signals can be from transducer interface like, LVDT, Strain gauge, Load cell, Torque transducer, function generator etc. 16 channel multiplexer is built into this device, and they are Microprocessor compatible logic levels.

DAD 31

The DAD-31 is 8 channel 12bit Analog to Digital Converter card using 7109 which interfaces with GCPU31A. It has also 8 bit digital to analog converter. It is used to study basics of Analog To Digital conversion & digital to analog conversion using Micro-controllers and develop real time process control applications.

The DAD-31 card incorporates a high performance CMOS, low power integrating A/D converter ICL7109.The ICL7109 provides the user with the high accuracy, low noise, low drift, versatility and economy of the 12-bit Dual slope integrating A/D converter. It is provided with Direct mode and UART handshake mode. The output data (12 bits, polarity and over range) may be directly accessed under control of two byte enable inputs and chip select input for a simple parallel bus interface. The RUN/HOLD input and status output allow monitoring and control of conversion timing. Here it is used in direct mode.

The PCB track design is shielded to keep low noise level in the analog paths and this card gives stable analog input readings.
