What is Digital I/O? This is an acronym for digital input and digital output and is used in computer control and automation applications. Sensing switch or contact closures is one example of digital input. This can be an array of buttons on a matrix keypad, or a simple push button, toggle switch, or proximity switch. Controlling relays, solenoids, or other actuators, are forms of a digital output and allow a computer to turn on and off external electrical devices. Our small low-cost Digital I/O cards that plug into an RS-232 or USB port are used as an interface between the software running on a computer and the hardware of the outside world.
