DESCRIPTION

The DIO24 ARD adds 24 digital I/O channels to an Arduino/Genuino UNO, MEGA 2560, or other (+5 Volt) compatibles. The specialized circuitry makes it easy to connect Solid-State I/O Racks, Switches, Relays, LEDs, and many other commonly encountered peripheral devices.

External devices connect to the DIO24-ARD through a single 50 conductor IDC ribbon cable style connector. The pin-out is fully compatible with standard 8, 16 and 24 position Solid State I/O module racks available from a variety of third-party vendors.

Each DIO24-ARD channel is individually defined through software to operate as either an input or output. Channels configured as outputs are capable of sinking 85ma.

The DIO24-ARD appears as a Serial-Peripheral-Interface (SPI) device. Only one Arduino digital output is required to function as the dedicated board Enable leaving all remaining Arduino digital I/O available for other purposes.

Get things up and running quickly with the supplied library. It includes routines for bit manipulation, port read and write, and controlling data direction.

FEATURES

  • 24 Individually programmable digital I/O channels
  • High output current capability (85ma sink)
  • Use supplied library or standard Arduino SPI 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
