The CM-DA-50 is a general purpose 24 channel Digital-to-Analog VMEbus board., incorporating features most demanded in today's first class military & industrial applications.
This board implements industry-standard TTL chips with easily obtainable D/A converters supplied by several leading vendors in all temperature ranges. This ensures availability of the module for long term applications.
The metallic layer within the PCB benefits heat dissipation & uniform component temperatures, thus increasing component longevity & module MTBF.
With individual external reference per channel, this module is well suited for applications requiring special voltage ranges or a wide variations in channel ranges.
Military versions with thermal overlay greatly improve capability to withstand shock & vibration.
The CM-DA-50 offers a highly flexible I/O cabling solution using VME64x connectors on both front panel and P2. Both connectors have identical pin-out.
All versions are compatible at the function level, Industrial versions allow low cost software development.
