NI PCIe-6509 Digital I/O Device: PCI Express, 96-Channel, 5 V, TTL/CMOS, 24 mA Digital I/O Device—The PCIe-6509 can directly drive external digital devices such as solid-state relays (SSRs). You can configure each port for input or output, and no external power supply is required for outputs.
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. If a computer or application fault occurs, the PCIe-6509 can use digital I/O watchdogs to switch to a configurable safe output state to ensure detection and safe recovery from fault conditions. Programmable input filters eliminate glitches/spikes and provide debouncing for digital switches/relays through a software-selectable digital filter.
National Instruments (NI) PCIe-6509 Digital I/O Device
► The PCIe-6509 (Part number: 779976-01) is an advanced Digital I/O Device from National Instruments. The device comes with 96 digital channels.
These channels are bidirectional in nature. The value of the current drive for each channel is 24 mili-amperes.
This device comes with the capability to drive external devices directly; this mainly includes the relays that are solid state.
It also offers the flexibility to configure any port as an input or output port for the data.
The NI PCIe-6509 Digital I/O Device also features programming capabilities, which allows the user to configure output parameters for different operational requirements.
► The NI PCIe-6509 Digital I/O Device has multiple accessories available, including cables and connectors of different types.
It enables the user to quickly set up the device. The instrument is also compatible with TTL Schmitt Triggers.
The user can also control the output power of the device with the help of software.
The NI PCIe-6509 device also has a protection mechanism against the input voltage. It has the maximum value of ± 20 volts.
This value is up to two pins of the NI PCIe-6509 Digital I/O Device.
► The NI PCIe-6509 Digital I/O Device has the voltage range of 0 to 5 volts for the digital inputs only.
The range for output voltages is from -0.5 to 5.5 volts. This model has a PCI Express bus connector. It also incorporates the in-house watchdogs.
It helps enable the mechanism to recover the instrument from fault state.
