Table 1. NI 6528 and PXI-6529 Specifications Overview
Overview and Applications
National Instruments 6528 and PXI-6529 devices are industrial
channel-to-channel isolated digital I/O interfaces for PCI and
PXI. You can use the optically isolated inputs of NI 6528 and
PXI-6529 devices to read the status of sensors, actuators, and logic
devices. NI 6528 devices have 24 solid-state relay outputs to switch
external devices with input currents up to 150 mA. With high current
drive and isolation, NI 6528 and PXI-6529 devices are ideal for a variety
of applications from automotive design, industrial factory automation,
and machine control to aerospace, laboratory research, and biomedical
applications. Industrial digital I/O devices are designed to incorporate
the latest hardware technologies for applications requiring ease of use,
high reliability, and performance. NI 6528 and PXI-6529 devices are
jumper-free and take advantage of NI-DAQmx measurement services
software to speed up application development with features such as
DAQ Assistant, automatic code generation, and high-performance
multithreaded streaming technology.
Hardware
Industrial Feature Set
NI industrial digital I/O devices provide a set of high-reliability features
designed to automate even the most demanding applications.
• Isolation offers an extended voltage range for direct connection
to industrial sensors and actuators
• Programmable power-up states provide safe operation
when connected to pumps/valves/motors/relays
• Digital I/O watchdog timers detect computer or application crashes
and ensure safe recovery
• Change detection triggers your application and performs a read
operation after a digital event with minimal processor usage
• Programmable input filters eliminate glitches/spikes and remove noise
• Industrial certifications from CE, FCC, C-Tick, UL, and VDE ensure EMI
compliance in most regions of the world and certify that the system
is safe to operate
