USB Module, Digital I/O

USB Digital I/O modules allow a PC to read or generate binary signals such as logic levels, switches, or digital device control. They are the simplest form of USB DAQ.

Specs include number of channels, supported voltage levels, and maximum update rate. Some models provide isolation to protect against noise or surges.

These modules are used for basic automation tasks like monitoring switches, controlling relays, or exchanging signals with external circuits in a quick, portable way.
