The 8 channel, 16-bit ADC Module provides up to 32 channels (four modules) of precision analog conversion for a wide variety of voltage sensors, millivolt bridge sensors and thermocouples allowing monitoring of temperature, pressure, strain, etc. during flight or on a static test stand.

Additional Info
Name: UFC-3C-ADC Analog to Digital Module
Description: The ADC Module provides 8 channels of 16-bit analog conversion for reading various user supplied sensors. Up to four of these modules are supported in a stack for a total of 32 channels of user data acquisition. Maximum sampling rate is 1,024 samples per second, all channels running. The 8-channel ADC is supplied a precision 0.05% reference which can be trimmed to a tighter tolerance. Each module occupies one decode space on SPI bus 0. In addition, each module has its own 8V precision regulated power supply for powering external sensors or providing the excitation voltage for millivolt bridge type sensors (pressure sensors and load cells). Additionally, the user may specify that the last channel on each module be used to monitor this voltage so that the exact excitation voltage can be automatically factored in the output calculation.
