AP445: Isolated Digital Output Module Description

AP445 isolated digital output modules provide 32 isolated solid-state relay outputs to safely control discrete devices.

A major AP445 advantage is its flexibility. The module supports wide range bipolar (AC or DC) voltage switching. Each port can be configured for high or low-side switches. The outputs are TTL-compatible when configured as low-side switches and populating on board pull up resistors  or using external pull-ups.

Isolation protects your computer system from noise, transient signals, and field wiring faults. Outputs are grouped into four 8-channel ports. Ports are isolated via solid-state relays from the logic and from each other.

Readback buffers simplify output status monitoring. And for easy closed-loop monitoring of critical control signals, use the AP445 with an AP441 input module.

Designed for COTS applications these isolated digital output modules deliver high-density, high-reliability, and high-performance at a low cost.

When used together, the AP441 input module and AP445 output module simplify loop-back monitoring of your critical signals.

AcroPack modules are RoHS compliant and ideal for military, defense, automation, aerospace, scientific, and development labs industries.

The AP445 series modules are 70mm long, this is 19.05mm longer than the full-length mini-PCIe card at 50.95mm. The board’s 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. Pin spacing and signal assignments will allow for 100V of port to port isolation. Logic and field lines are isolated from each other for voltages up to 250V AC or DC on a continuous basis.

The AP445 series maintains the same functionality and memory map of the existing Industry Pack modules providing a smooth transition to the AcroPack I/O modules.
