AP471 AcroPack I/O (AP) modules provide 48 general-purpose, bidirectional I/O points to economically monitor and control a large quantity of digital devices. Each channel has interrupt capability for detecting low-to-high or high-to-low transitions. Change- of-state interrupts are supported using paired channels. Debounce eliminates interrupts from noise and switching transients for error-free edge detection.
AP471 outputs are full-featured. They provide closed-loop read back status monitoring. TTL level thresholds and 15mA sink capability allow a direct interface to standard relay racks. For safety, outputs go to a failsafe state upon power up/ reset without any instantaneous toggling to prevent false alarms.
Designed for COTS applications these TTL level digital I/O modules deliver high-density, high reliability, and high-performance at a low cost. AcroPack modules are RoHS compliant and ideal for military, defense, automation, aerospace, scientific, and development labs industries.
The AP471 module is 70mm long, this is 19.05mm longer than the full length mini PCIe card at 50.95mm. The boards width is the same as mPCIe board of 30mm and they use the same mPCIe standard board hold down standoff and screw keep out areas.
A down facing 100 pin Samtec connector will mate with the carrier card. Fifty of these signals are available as field I/O signals. The AP471 maintains the same functionality of the existing Industry Pack modules providing a smooth transition to the AcroPack I/O modules.
