DESCRIPTION

The DIO24-ARD is a 24-Bit (channel) digital Input/Output interface designed for Arduino UNO, MEGA 2560, and compatible devices. All channels can be individually defined through software to operate as either an input or output. Channels configured as outputs are capable of sinking 85ma. External devices connect to the DIO24-ARD through a single 50 conductor IDC ribbon cable style connector. The pin-out of this connector is fully compatible with standard 8, 16 and 24 position Solid State I/O module racks available from a variety of third party vendors. The DIO24-ARD is also designed to easily interface other common devices such as switches, relays, contacts, and LED's.

FEATURES

  • 24 Individually programmable digital I/O channels
  • High output current capability (85ma sink)
  • Uses standard Arduino SPI software library functions
  • Jumper selectable Enable signal selection
  • Stack-Through connectors accommodate multiple shields
  • Drives industry standard Solid State I/O Module Racks and other peripheral devices
