Introducing the CIO-EXP32
Overview: CIO-EXP32 features
The CIO-EXP32 is a 32-channel signal conditioning accessory board supported under popular Microsoft
®
Windows
®
operating systems.
The CIO-EXP32 is used to expand the number of analog inputs and the range of amplification of DAS08 and
DAS16 series boards. Using multiple CIO-EXP32 boards, a 16 channel A/D board can be expanded to up to
256 inputs; an 8 channel A/D board can be expanded to up to 128 inputs.
The CIO-EXP32 board has two banks of 16 differential inputs that are multiplexed into one single-ended output
channel. Four digital inputs are controlled by the A/D board's digital outputs, and are used to select one of the
multiplexed channels for output. An on-board semiconductor sensor provides a cold junction compensation
(CJC) reference for thermocouple applications.
You select one channel on the A/D board to send the multiplexed analog output to. In addition, you can output
the CJC signal to a second A/D board channel. You can enable an input filter, ground reference, and open
thermocouple detect options for each channel using on-board solder gap switches. You specify the gain of the
multiplexer with an onboard gain switch.
You can power the CIO-EXP32 internally from the A/D board, or externally from the computer's +5 V power
supply connectors.
The CIO-EXP32 board is mounted externally to the PC. It can be placed in the open on a benchtop or in a case.
