AP441 modules provide 32 optically isolated inputs to safely monitor a wide range of digital input voltage levels.

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

Change-of-state, high-to-low and low-to high interrupts are individually programmable for each channel. Debounce eliminates spurious interrupts from noise and switching transients for error-free edge detection

Closed-loop monitoring of critical control signals is easily accomplished using the AP441-XE-LF in conjunction with Acromag’s AP445E-LF digital output module.

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

The AP441 module is 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 AP441 series maintains the same functionality of the existing Industry Pack modules providing a smooth transition to the AcroPack I/O modules.
