The EXC-4000P104Plus/xx card for PC/104 Plus systems supports up to forty Discrete channels using the M4KDiscrete module. The module provides a complete solution for developing and testing discrete voltage-level interfaces. The M4KDiscrete contains control I/O registers that are memory-mapped and may be accessed in real time. The module supports twenty programmable I/O discretes that can record or control the external discretes that are connected to it. In addition, the module can record changes in the input discrete with an associated time tag via a built-in FIFO. Output discretes are open collector, capable of handling up to 32V with a maximum sink current of 100 mA each.
The user can set each discrete:

• Either as input or output.

• Either to TTL (0 – 5V) or Avionics (0 – 32V) voltage levels on inputs and

• Either enable or disable external debounce on inputs

There is a 4092 Word FIFO (a string of 1023 discrete entries) containing the data and time tags.

The EXC-4000P104Plus/xx is supplied with C drivers, including source code and  may be used with Exalt, Excalibur’s Analysis and Laboratory Tools, a Windows monitoring application. Mating connector provided for I/O connection.

Please see multi protocol 4000 modules for additional information on protocols that can be added to this card.
