Product short description:
  • 32 Digital I/O Channels
  • High impedance
  • PCIe Bus Interface

The AP408 monitors or controls the on/off (high/low) status of up to 32 devices. Each channel can be used as an input or output.

AP408: High Voltage Digital Input/Output Module Description

The AP408 monitors or controls the on/off (high/low) status of up to 32 devices. Each channel can be used as an input or output.

All 32 input channels can be configured with interrupts for a change of state or level detection of any bit. The TTL input threshold includes hysteresis for increasing noise immunity.

In order to ensure safe, reliable control under all conditions, output operation is “fail-safe.” That is, the outputs are always off upon power-up and are automatically cleared following a software reset.

Loopback monitoring of critical control signals is easy since the input and output circuitry are connected in tandem to each channel.

Designed for COTS applications these 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 AP408 is 70mm long, this is 19.05mm longer than the full length mini PCIe card at 50.95mm. The board width is the same as 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 will mate with the carrier card. Fifty of these signals are available as field I/O signals. Pin spacing and signal assignments will allow for 100V of signal to signal isolation.

The AP408 maintains the same functionality and memory map of the existing Industry Pack modules providing a smooth transition to the AcroPack I/O modules.

AP408: High Voltage Digital Input/Output Module Benefits & Features

  • PCI Express Generation 1 interface
  • 32 digital input/output channels
  • 0 to 60V DC input range, 60V DC low-side switch outputs
  • Outputs sink up to 1A per channel
  • TTL-compatible input threshold with hysteresis
  • Change-of-state/level interrupts (up to 32)
  • Buffered inputs include hysteresis to increase noise immunity.
  • Interrupts are software-programmable for a change of state or level detection.
  • Loopback monitoring enables self-test and fault diagnostics to detect open output switches or shorts.
  • High impedance inputs prevent loading of the input source and minimize current.
  • Individual outputs sink up to 1A DC continuous. No deration of output current required at elevated temperatures.
