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.
Features
- 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 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.
- 0...+70°C or -40...+85°C (-E models)
