Product Description

The NI SCXI-1326 is a high-voltage terminal block designed to work specifically with certain NI SCXI switch modules, such as the SCXI-1162, SCXI-1162HV, SCXI-1163, and SCXI-1163R. It is not a data acquisition module itself, but rather a shielded accessory that simplifies the connection of high-voltage and high-current signals to a compatible SCXI module. The terminal block features screw terminals, making it easy to wire signals from your external equipment to the SCXI system.

Product Specifications

• Maximum Voltage Handling: 300 V, Category II
• Number of Terminals: 48 screw terminals (arranged in 8 groups of 6)
• Compatibility: Specifically designed for use with NI SCXI-1162, SCXI-1162HV, SCXI-1163, and SCXI-1163R modules.
• Isolation: Provides common-mode isolation of 300 Vrms between banks and between banks and earth.
• Connection Type: Screw terminals for easy, secure wiring.
• Safety Features: Includes a safety earth ground solder lug for connecting a safety ground wire.

Product Advantages

The SCXI-1326 offers several key benefits, particularly in applications involving high-voltage switching:

• High-Voltage Signal Connectivity: It provides a safe and reliable way to connect high-voltage signals up to 300 V to your SCXI switch module. This is critical for applications in industrial automation and power systems.
• Simplified Wiring: The screw terminals make it straightforward to connect and disconnect wires, which simplifies setup and maintenance compared to other connection methods.
• Enhanced Safety: The terminal block is a shielded board with a dedicated safety ground, which helps to protect against electric shock and provides a robust ground reference for the high-voltage signals.
• Module-Specific Design: It is engineered to mate perfectly with its compatible SCXI switch modules, ensuring a secure physical and electrical connection.

Applications

The SCXI-1326 is used in any application that requires the switching of high-voltage or high-current signals within a SCXI system. Common applications include:

• Automated Test Systems: Switching power supply signals, high-voltage relays, and other industrial loads in a test environment.
• Industrial Automation: Routing and controlling signals to and from industrial equipment, such as motors and solenoids.
• High-Power Component Testing: Interfacing with components that operate at higher voltages and currents.

Important Considerations

For proper and safe operation, keep these points in mind when using the SCXI-1326:

• Module Compatibility: The SCXI-1326 is an accessory and must be used with a compatible SCXI switch module. It is not a standalone device and will not function with all SCXI modules. For example, it is not recommended for use with the SCXI-1161 module.
• Safety Ground: When dealing with high voltages (≥30 Vrms), it is mandatory to connect a safety earth ground wire to the terminal block’s safety ground solder lug. This is a critical safety measure to protect against electrical shock.
• Proper Wiring: When connecting signal wires, strip no more than 7 mm of insulation and ensure that no bare wire extends past the screw terminal. This prevents short circuits. Always turn off power to the signal lines before connecting or disconnecting wires.
• Operating Environment: The module is designed for a specific temperature range. Ensure it is used in a suitable environment to prevent damage.
