AP570: MIL-STD-1553 Communication Module

AP570: MIL-STD-1553 Communication Module

The AP570 MIL-STD-1553 communication 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 utilizes 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.

Options (Contact factory for ordering): Direct coupled MIL-STD-1553 bus. | Safety critial monitoring only (Tx inhibit). | Polyurethane conformal coating.

The AcroPack® product line updates our popular Industry Pack I/O modules with a PCIe interface format. This tech-refresh design offers a compact size, low-cost I/O, and a rugged form factor. Combining different AcroPack module types on one XMC, VPX, or PCIe carrier allows for a simplified modular approach to system assembly.

Designed for COTS applications these avionics communication mezzanine modules deliver high-density, high-reliability, and high-performance at a low cost.

The AP570 MIL-STD-1553 communication modules are 70mm long, which is 19.05mm longer than the full-length mini PCIe card at 50.95mm. The board’s width is the same as an mPCIe board of 30mm and uses the same mPCIe standard board hold down standoff and screw keep-out areas.

A down-facing 100-pin Samtec connector mates with the carrier card. This ensures a secure connection for your I/O without the vulnerabilities of cabling.
