The SMP7500 is a high-performance I/O module with twelve groups of 8 bits (96 channels). Each group of 8 bits may be configured as an input or output under program control or via the front panel control line. The I/O may be either single buffered to provide real time data access or double buffered to provide synchronized data. Being part of the SMIPII™ series, up to 192 channels can be accommodated in a single-slot C-size card, or 576 channels in two VXIbus card slots.

The SMP7500 has the flexibility to source the input and output clocks from the front panel, allowing very large numbers of channels to be synchronized to collect or present data to a UUT. Additionally, the on-board SMIPII™ memory can be used to turn the SMP7500 into a memory backed word generator. In order to ease overall system cabling, all clamping diodes and open collector channels can be pulled up internally, rather than on a per-channel basis.

Each channel can sink 300 mA, and includes built-in clamping diodes, making this module ideal for driving and sensing external devices such as relays. Additionally, for relay driving, the SMP7500 supports all key features of the SMIPII™ family such as, scan lists, timing delays etc.
