Digital I/O
Digital I/O DAQ (Data Acquisition) devices are systems designed to manage and monitor digital signals in various applications. These devices can send and receive digital data, making them essential for tasks like controlling external hardware, monitoring digital states, or interfacing with other electronic systems. They are commonly used in automation, testing, and industrial processes where precise digital control or monitoring is required.
The "I/O" in their name refers to "input" and "output," indicating their dual functionality. Digital input channels allow the device to detect and monitor the state of digital signals, such as the on/off status of switches or the logic levels of circuits. Digital output channels enable the device to control or trigger external components, such as LEDs, motors, or relays, by sending specific digital signals.
