The CM-DI-40 is a general purpose 64 channel optocoupled input VMEbus board, incorporating features most demanded in today's first class military & industrial applications.
The board implements a complete input voltage stage per channel, featuring overvoltage protection, galvanic isolation, rectifier & filter and easy configuration to accept a wide range of AC/DC voltage levels.
The metallic layer within the PCB benefits heat dissipation & uniform component temperatures, thus increasing component longevity & module MTBF.
Incorporating Built-In-Test circuitry for testing all on board TTL chips using wraparound loops which read-back channel status to verify correct module operation.
Military versions with thermal overlay greatly improve capability to withstand shock & vibration.
The CM-DI-40 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.
