| XIP-2440 Isolated Digital Input Modules
 XIP-2440 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 XIP-2440 in conjunction with Xycom Automation's XIP-2445 digital output module.
XIP-2440 Features:
- 32 port-isolated input channels
- 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)
Three input ranges (different models):
- XIP-2440-001: ±4 to ±18V DC or AC peak
- XIP-2440-002: ±16 to ±40V DC or AC peak
- XIP-2440-003: ±38 to ±60V DC or AC peak
Benefits:
- Software configuration allows on-the-fly changes without removing modules.
- Pins are compatible with XIP-2445 output module for loopback monitoring.
- Loopback monitoring enables self-test and fault diagnostics to detect open switches or shorts.
