Product short description:
  • 48 bi-directional input/output channels
  • TTL-compatible inputs
  • CMOS-compatible open-drain outputs
  • Interrupt support for each channel

IP470A Industrial I/O Pack (IP) modules provide 48 general-purpose, bidirectional I/O points to economically monitor and control a large quantity of digital devices.

IP470A: Digital Output Module, TTL Level Description

Each channel has interrupt capability for detecting low-to-high or high-to-low transitions. Change-of-state interrupts are supported using paired channels. Debounce eliminates interrupts from noise and switching transients for error-free edge detection.

IP470A outputs are full-featured. They have socketed pull-ups and provide closed-loop readback status monitoring. TTL level thresholds and 15mA sink capability allow a direct interface to standard relay racks. And for safety, outputs go to a failsafe state upon power-up/reset without any instantaneous toggling to prevent false alarms.

Benefits

  • Output readback capability eliminates the need for additional input channels toverify the output channel state.
  • Pinouts are compatible with industry-standard isolated I/O racks.
  • Output channels do not “glitch” after a power-up/reset to eliminate false alarms.

The IP470A is a drop-in replacement for the IP470, please see the known differences document below for more information.
