Acromag IP440-x Isolated Digital Input Module

  • 32 Port-Isolated Input Channels
  • Interrupt Support for Each Channel
  • High Speed Processing (0 Wait States)
  • Programmable Polarity of Event Interrupts
  • Programmable Debounce
  • Reverse Polarity Protection


The Acromag IP440-x Isolated Digital Input Module provides 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 interrupts are supported using paired channels. 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 IP440 in conjunction with Acromag's IP445 digital output module.

Product Family: IP440-x, IP440, IP440-1

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
