Digital I/O
Digital I/O  
Digital I/O cards and modules let you sense and control binary (on/off, high/low) signals. Most models are commonly used to control devices and sense switch closures, while others provide high-speed pattern generation, timing and event counting. Models with current sink capacity of 8mA or more can be used to directly switch solid-state relays, while other models have built-in relays for direct connection to field voltages.
