 DESCRIPTION |
| q |
The CM-DI-40 is a general purpose
64 channel optocoupled input VMEbus board. This professional module offers an
outstanding design which incorporates features most demanded in today's first
class military and industrial applications. |
|
| q |
It incorporates specific
Built-In-Test circuitry which allows testing all on board TTL chips. Wraparound
loops disconnect external application signals and connect internal test signals
in order to verify correct module operation. |
| q |
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. |
| q |
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-outs. |
| q |
Military versions,
provided with conduction cooled thermal overlay, greatly improve capability to
withstand shock and vibration. |
|
|
| q |
The metallic layer in
the PCB also benefits heat dissipation and allows all components to work within
homogeneous temperatures, thus greatly increasing component longevity and
module MTBF. |
| q |
All CM-DI-40 versions
are 100% compatible at the functional level, allowing software development to
proceed with low cost Industrial versions. |
