The National Instruments PCI-6230, part number 779615-01, is a multifunction data acquisition card for PCI systems. It provides isolated analog input, analog output, digital I O, and counter functions. The card is designed for industrial measurement, automated test, laboratory automation, and control applications that require signal isolation.
The PCI-6230 installs in a desktop computer or industrial PC. Isolation helps protect the DAQ system from voltage differences and noise in industrial environments. Engineers can acquire sensors, generate outputs, and monitor digital signals with one card.
Isolated Analog Input
The PCI-6230 provides analog input channels with isolation. Isolation helps reduce ground loop problems and supports sensors with different references. Input range and sample rate can be configured for different signals.
Engineers should verify isolation ratings and wiring requirements. Shielded cable and proper grounding improve signal quality. The card should be used within its specified electrical limits.
Analog Output and Digital I O
The card includes analog output channels for stimulus generation and control. Digital I O lines support status monitoring, relay control, and communication with digital devices. Counter functions support event counting, pulse generation, and frequency measurement.
These functions can be synchronized with analog acquisition. Engineers should plan timing and triggering for correlated measurements.
PCI Integration and Timing
The PCI-6230 installs in a compatible PCI slot. It communicates with the host computer through the PCI bus. The card supports hardware timing and triggering for coordinated acquisition and output.
Software and Driver Support
The card is designed to work with NI data acquisition software and standard programming environments. Engineers can configure channels, create tasks, set timing, and read data using supported drivers and APIs.
Applications
The PCI-6230 is suited to industrial monitoring, automated test, sensor measurement, and control system validation. It supports isolated multi channel measurement in a PC based system.
Installation and Maintenance
Installation requires a compatible PCI slot, driver installation, and connection of field wiring or terminal blocks. Proper grounding and shielding help maintain signal quality. The computer enclosure should provide adequate cooling.
Maintenance includes checking cable connections, verifying channel configuration, and confirming calibration status. Documentation helps repeatability.
Summary
The National Instruments PCI-6230 Multifunction DAQ Card provides isolated analog input, analog output, digital I O, and counters for PCI systems. It supports industrial measurement, automated test, and control applications. The PCI-6230 is a practical DAQ card for engineers who need isolation and multifunction measurement.
