IP440A:
Digital Input Module, Isolated
• 32 port-isolated input channels
• ±60V AC/DC input (three ranges)
• Interrupt support for each channel
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.
