The National Instruments PXI-6704 is a PXI analog output module with 16 bit resolution and static digital I O. It provides multiple analog output channels for control, stimulus generation, and automated test. The module is used in PXI systems that require precise voltage or current outputs alongside digital signals.
Analog output modules drive setpoints, valves, actuators, and test stimuli. The PXI-6704 brings multi channel output capability to the PXI platform. Engineers can combine it with analog input and digital modules for closed loop test and control.
Analog Output Channels
The module provides multiple analog output channels with 16 bit resolution. Outputs can be configured for voltage or current mode depending on the model configuration and application. Engineers should verify load impedance, output range, and wiring.
Outputs should be set to safe values at startup and shutdown. Proper grounding and shielding help reduce noise. The module should be used within its specified limits.
Static Digital I O
The PXI-6704 includes static digital I O lines for status monitoring and control. Digital lines can interface with relays, switches, and indicators. Engineers should verify voltage levels and drive requirements.
PXI Integration
The module operates in compatible PXI chassis. It can be combined with controllers, digitizers, and switches. The PXI backplane supports timing and triggering for multi module systems.
Applications
The PXI-6704 is suited to control systems, test fixtures, stimulus generation, and laboratory automation. It supports multi channel analog output in a PXI system.
Installation and Maintenance
Installation requires a compatible PXI slot and field wiring according to the product documentation. Output wiring should be labeled and secured. The chassis should provide adequate cooling and protection.
Maintenance includes checking terminals, verifying output values, and confirming calibration. Documentation of channel assignments helps reliable operation.
Summary
The National Instruments PXI-6704 Analog Output Module provides 16 bit analog output and static digital I O for PXI systems. It supports control, stimulus, and automated test applications. The PXI-6704 is a practical module for engineers who need multi channel output in a PXI platform.
