The CM-AD-45 is a general purpose 32 channel A/D (Analog to Digital) board that incorporates features most demanded in first class military and industrial applications.
On-board auto-conversion circuitry performs all tasks relative to multiplexing, sampling & converting of analog input signals.
Dual port RAM acts as a transparent communications device between the A/D converter and the VMEbus.
Extensive Built-In-Test per channel is based on a wraparound loop that disconnects external analog input signals and connects internal test signals in order to verify correct module operation.
The metallic layer within the PCB benefits heat dissipation & uniform component temperatures, thus increasing component longevity & module MTBF.
CM-AD-45 offers a flexible I/O cabling solution using connectors on the front panel & P2. Military versions with thermal overlay greatly improve capability to withstand shock & vibration.
All versions are compatible at the function level, Industrial versions allow low cost software development.
