CM-DIO-40

The CM-DIO-40 is a universal 32 input plus 32 output discrete VMEbus board, incorporating features most demanded in first class military and industrial applications.

CM-DIO-40 - Discrete Input/Output

All input channels feature overvoltage protection, galvanic isolation, rectifier & filter and configuration for a range of AC/DC voltage levels.

All output channels can be factory fitted to support a choice of 11 different device configurations. Relay, Optocoupler, PhotoMOS & SSR versions are isolated.

Built-In-Test is based on wraparound loops that disconnect external signals and connect internal test signals in order to verify correct module operation.

CM-DIO-40 - Discrete Input/Output

The metallic layer within the PCB benefits heat dissipation & uniform component temperatures, thus increasing component longevity & module MTBF.

Military versions, provided with conduction cooled thermal overlay, greatly improve capability to withstand shock and vibration.

The CM-DIO-40 offers a highly flexible I/O cabling solution using VME64x connectors on the front panel and P2. Both connectors have identical pin-outs.
