Industrial digital I/O offers USB connectivity

Tag : industrial portable computer

With programmable power-up states, engineers can pre-define thestate in which the USB-6509 device powers up to ensure reliableoperation when connected to industrial actuators such as pumps,valves, motors or relays. Digital I/O watchdog timers can detect avariety of fault conditions such as a computer crash, andautomatically respond by setting the outputs to a user-defined safestate.
 
With change detection, the device automatically triggers anapplication to perform a read operation after a digital linechanges state. It can also eliminate unintended glitches and spikesin input data and avoid false readings caused by noise withprogrammable input filters.
 
The 96-channel device is compatible with TL, CMOS and 5-V digitallogic levels, and each port of eight lines is individuallyconfigurable for input or output. The USB-6509 can drive externaldigital devices such as solid-state relays (SSRs) with current upto 24 mA per line while pull-up and pull-down resistors included onthe device stabilize the bus potential during a non-access state.The bus-powered device can source up to 215 mA total across alldigital output lines. An optional 12-Vdc power supply is availablefor additional sourcing current.
 
The USB-6509 works with NI-DAQmx driver software, which features aneasy-to-use and intuitive interface for programming. The device isalso compatible with NI LabVIEW, NI LabWindows/CVI, ANSI C/C++,Visual Basic .NET, C# and Visual Basic 6.0.
Pricing: The NI USB-6509 is priced from $449.
