NI+PXI-8423

Description

The NI PXI-8423 Module is a 2 or 4-port Isolated RS-485 Interface designed for use with PXI (PCI eXtensions for Instrumentation) chassis in various test, measurement, and automation applications. It is manufactured by National Instruments (NI).

Product Name: NI PXI-8423 Isolated RS-485 Interface Module

Product Description:

This module allows PXI systems to:

• Communicate with devices that use the RS-485 serial communication standard. These devices are commonly found in:
  • Industrial automation systems
  • Process control systems
  • Data acquisition systems
  • Environmental monitoring systems
• Provide electrical isolation between the PXI system and the RS-485 network, protecting the PXI system from potential ground loops and electrical noise that can disrupt communication and damage equipment.

Key Features:

• Number of ports: Available in two versions:
  • PXI-8423: Offers 2 DB9 male connector ports.
  • PXI-8423/4: Provides 4 RJ45 male connector ports.
• Isolation voltage: Offers 2000 VDC of galvanic isolation between the PXI system and the RS-485 network, enhancing safety and reducing noise interference.
• Data transfer rate: Supports data transfer rates up to 460 kbps.
• Driver and software support: Compatible with NI LabVIEW and other development environments for programming communication functions.

Additional Information:

• The specific functionalities and configuration options might vary depending on the model (2-port or 4-port) and the software environment used.
