MIL-STD-1553 Communication for AcroPack I/O

AP570: MIL-STD-1553 Communication

• One dual redundant MIL-STD-1553 Communication Channel
• Extended temperature
• PCIe bus interface

Acromag modules provide a dual redundant MIL-STD-1553 channel with four open/ground avionics level (+35V) discrete I/O signals in addition to IRIG-B input and Trigger I/O. Hard wired RT address signal input pins are also available at the connector.

This Acropack card utilises the latest AIM Common Hardware Core derived from the field proven MIL-STD-1553 interface to deliver low power consumption and high performance for rugged environments and embedded applications.

AP571-000: Single function MIL-STD-1553.
AP572-000: Full multi-function MIL-STD-1553.
