Using programmable power-up states, you can configure the initial output states in software to ensure glitch-free, safe operations when connected to industrial actuators (pumps/valves/motors/relays).
For applications that require onboard pull-up resistors, consider the NI PCI-DIO-96 parallel digital I/O board.
If a computer or application fault occurs, the PCI-6509 can use digital I/O watchdogs to switch to a configurable safe output state to ensure detection and safe recovery from fault conditions when connected to industrial actuators. With change detection, the digital I/O board notifies and triggers your software application when a digital change of state occurs (without polling). Programmable input filters eliminate glitches/spikes and provide debouncing for digital switches/relays through a software-selectable digital filter.
NI-DAQmx software technology includes the DAQ Assistant to create your application with no programming. NI-DAQmx makes it fast and easy to configure your device and take advantage of all the high-reliability industrial features in NI LabVIEW, ANSI C, Microsoft Visual C++, or Microsoft .NET languages (C# and Visual Basic .NET).
