The CYEXP
16 is a signal conditioning accessory board that expands the number of
analog inputs and the range of amplification of the CYDAS 8, 800, 1200, 1600 and
CYDAS 16 family of boards. Used with an 8-channel A/D board, CYEXP panels can be
daisy-chained to provide up to 128 inputs. Your A/D board selects the CYEXP
input to be read using 4 digital output lines.
The CYEXP 16 has 16 inputs in one bank, which is connected to a jumper block
labeled "EXP Output to DAS." The bank of 16 inputs is multiplexed to one output
channel. This output from the CYEXP 16 is connected to one analog input of the
A/D board in your computer. The analog input channel on your A/D board must be
single-ended to be compatible with the CYEXP. The CYEXP 32 is
two CYEXP 16s on one panel, multiplexing 32 differential input channels onto
two single-ended A/D channels on your DAS board
An on-board Cold Junction Compensation (CJC) sensor can be mapped to an
unused A/D channel to increase the accuracy of thermocouple readings if some of
your signals are from thermocouples.
The CYEXP 16L and CYEXP 32L are the same as the regular CYEXP boards, but
they use lift-off terminal strips. This is useful for data acquisition systems
that must be shared between applications.
Input gain is selected for each bank of 16 channels. The on-board gain
amplifier can provide gains of 1, 10, 100, 200, and 500. These gains are
selected via a DIP switch, and are additive - by setting both the 500 and the
200 switch ON, you achieve a gain of 700. Gain range should be set to provide an
output in the ±5V (preferred) to ±10V (max) range. As this is an
analog-to-analog panel, the output range is directly related to the input signal
and the gain setting. Of course, if no gain is selected, signals are passed
straight through without amplification (gain=1).
The CYEXP family also features 8-channel
RTD and bridge, 16-channel
RTD, or bridge
completion multiplexing panels.
Note: Our CYEXP 32L-5PK is
special order, for a pack of five multiplexing panels. (If you need more than
five, please call.) Leadtime approximately 8 weeks. Sorry, no returns on this
item. |
