The GX5731 is a 6U modular digital I/O card with 224 I/O channels. Designed for ATE, data acquisition, or process control systems where a large number of discrete I/O channels are required, the GX5731 offers the highest density in the industry for a single PXI plug-in board. Of the 224 channels, 128 support TTL levels with the direction of each group of eight channels programmable as input or output. The other 96 channels can be used for customized I/O using MTS’ GX57xx series I/O modules.
