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.
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.
Input gain is selected for each bank of 16 channels. The on-board gain amplifier can provide gains of 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, as well as a 32-channel multiplexing terminal panel.
Note: Our CYEXP 16L-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.
