IP440A: Digital Input Module, Isolated

IP440A: Digital Input Module, Isolated Description

IP440A Industrial I/O Pack (IP) 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 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 IP440A in conjunction with Acromag’s IP445 digital output module.

The IP440A is a drop-in replacement for the IP440, please see the known differences document below for more information.

Update to AcroPack mezzanine modules into your host system, they maintain the same functionality and memory map of Acromag’s existing Industry Pack (IP) modules. Learn More >

IP440A: Digital Input Module, Isolated Features & Benefits

• 32 port-isolated input channels
• Three input ranges (different models):
  • IP440A-1: ±4 to ±18V DC or AC peak
  • IP440A-2: ±16 to ±40V DC or AC peak
  • IP440A-3: ±38 to ±60V DC or AC peak
• Interrupt support for each channel
• High-speed processing (0 wait states)
• Programmable polarity of event interrupts (low-to-high or high-to-low transitions)
• Programmable debounce
• Input hysteresis
• Reverse polarity protection
• Software configuration (no jumpers or switches)
• 0 to 70°C (IP440A-1/2/3) or -40 to 85°C (IP440A-1E/2E/3E models)
• Software configuration allows “on-the-fly” changes without removing modules.
• Pins are compatible with IP445 output module for loopback monitoring
• Loopback monitoring enables self-test and fault diagnostics to detect open switches or shorts.
