Getting to Know Your
NI 6509/651x/6520/6521/6528
Device
The NI 6509 is a 96-bit, high-drive digital input/output (DIO) device for PCI, PXI, and
CompactPCI chassis. The NI 6509 features 96 TTL/CMOS-compatible digital I/O lines,
24 mA high-drive output, and the industrial DIO feature set. For more information on the
industrial DIO feature set, refer to the
The NI 651x devices are 30 V bank isolated data acquisition (DAQ) devices for PCI, PXI, or
CompactPCI chassis. The NI 651x devices feature either 64 or 32 channels of various channel
count input/output signaling for sourcing (NI 6510/6512/6514/6516/6518) or sinking
(NI 6511/6513/6515/6517/6519) current. The NI 651x devices also provide the industrial
DIO feature set. For more information on the industrial DIO feature set, refer to the

NI 651x devices.
The NI 6520/6521 devices contain five Form A single-pole single-throw (SPST) non-latching
relay outputs, three Form C single-pole double-throw (SPDT) non-latching relay outputs, and
eight channel-to-channel isolated industrial inputs. The NI 6520/6521 devices provide
16 channels of digital I/O (eight optically isolated digital input channels and eight
non-latching relay output channels), and the industrial DIO feature set. For more information
on the industrial DIO feature set, refer to the
The NI 6528 device provides 24 isolated input channels, 24 isolated output channels,
real-time system integration (RTSI) capabilities, and the industrial DIO feature set. For more
information on the industrial DIO feature set, refer to the
NI 6528 is ideal for 60 V isolation and switching in both industrial and laboratory
environments.
