The CM-SD-40 is a general purpose high density input VMEbus board, incorporating 16 Synchro/Resolver channels & features most demanded in first class military & industrial applications.
Input channels incorporate auto-conversion circuitry that fills a Dual port RAM with the latest conversion data. All I/O channels support most common S/R voltage ranges used in military and avionics equipment.
Incorporating Built-In-Test that is based on wraparound loops that disconnect external S/R signals and connect 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. All versions are compatible at the function level, Industrial versions allow low cost software development.
The CM-SD-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.
