The CM-DA-40 is a general purpose Digital-to-Analog VMEbus board, incorporating features most demanded in today's first class military and industrial applications.
This board implements industry-standard TTL chips with easily obtainable D/A converters supplied by several leading vendors in all temperature ranges, ensuring long term availability.
With individual external reference per channel, this module is well suited for applications requiring special voltage ranges or wide variations in channel ranges.
The metallic layer within the PCB benefits heat dissipation & uniform component temperatures, thus increasing component longevity & module MTBF.
The CM-DA-40 offers a highly flexible I/O cabling solution using both 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.
