NI SCXI-1300

Product introduction

The National Instruments SCXI – 1300 is a crucial general – purpose terminal block within the SCXI product family. It serves as a fundamental link between various signal sources and SCXI modules, playing a pivotal role in industrial automation and test – measurement systems. With its 72 screw terminals, it offers a convenient and reliable way to establish connections.

This terminal block can be used to connect input signals to a range of SCXI modules such as the SCXI – 1102 series, SCXI – 1104, and SCXI – 1100. It also features an onboard temperature sensor for cold – junction compensation, which is especially useful in thermocouple – based temperature measurement setups. The SCXI – 1300 is designed to be mounted directly to the front of SCXI modules, providing a compact and organized solution for signal connection and disconnection within an automation system.

Core advantages and technical highlights

Convenient Signal Interconnection: The SCXI – 1300 simplifies the signal connection process with its numerous screw terminals. The 32 pairs of screw terminals dedicated to input signals allow for easy connection of multiple sensors or signal sources to compatible SCXI modules. This makes it highly suitable for applications where a large number of signals need to be routed, such as in complex industrial monitoring systems.

Cold – Junction Compensation: The integrated cold – junction sensor is a significant advantage. In thermocouple applications, accurate temperature measurement depends on proper cold – junction compensation. With an accuracy of ±1.3°C in the 0 – 50°C range and a repeatability of ±0.5°C, the SCXI – 1300 ensures precise temperature readings. The 10mV/°C output of the sensor provides a reliable signal for compensating the thermocouple measurements.

Shielded Design: It is fully shielded, which helps in reducing electromagnetic interference. This is crucial in industrial environments where there are often many electrical devices that can generate noise. The shielded design ensures that the signals being routed through the SCXI – 1300 remain clean and accurate, improving the overall performance of the automation system.

Compliance with Safety Standards: Meeting multiple international electrical safety standards like IEC 61010 – 1, EN 61010 – 1, UL 61010 – 1, and CAN/CSA – C 22.2 No. 61010 – 1, the SCXI – 1300 guarantees safe operation in various settings. This compliance gives users peace of mind when integrating it into their systems, whether in industrial plants, research laboratories, or other applications.

Typical application scenarios

Industrial Monitoring: In industrial plants, the SCXI – 1300 is used to connect sensors for monitoring various parameters. For example, in a manufacturing facility, it can link temperature sensors (using thermocouples) to SCXI modules for real – time temperature monitoring of production processes. The cold – junction compensation feature ensures accurate temperature readings, which is vital for maintaining product quality. It can also connect pressure sensors and vibration sensors to SCXI modules, enabling comprehensive equipment health monitoring.

Research and Development: In research laboratories, the SCXI – 1300 is valuable for test – measurement setups. When conducting experiments that involve measuring multiple physical quantities, such as in materials research where temperature, strain, and electrical signals need to be measured simultaneously, the SCXI – 1300 can connect all these sensors to the appropriate SCXI modules. Its shielded design protects the sensitive signals from the electromagnetic noise often present in laboratory environments, ensuring reliable data collection.

Building Automation: In large commercial buildings, the SCXI – 1300 can be used in building automation systems. It can connect sensors for temperature, humidity, and air quality to SCXI modules. These modules then send the data to a central control system for intelligent building management. The easy – to – use screw terminals make it convenient for installation and maintenance in building electrical closets.

Installation, commissioning and maintenance instructions

Installation Preparation: Before installing the SCXI – 1300, ensure that the working environment is clean and free from excessive dust and moisture, as per its environmental requirements of 10% – 90% non – condensing relative humidity and an operating temperature of 0 – 50°C. Tools required include a 1/8 in. flathead screwdriver, number 1 and 2 Phillips – head screwdrivers, a wire insulation stripper, long – nose pliers, and a wire cutter. Safety precautions should be taken, such as turning off the power to the SCXI system to avoid electrical shocks during installation. Mount the SCXI – 1300 to the front of the compatible SCXI module, ensuring it is properly aligned and securely fastened.

Maintenance Suggestions: For daily maintenance, regularly inspect the terminal block for any signs of loose connections. Loose screws can cause signal interruptions or inaccurate readings. Check for corrosion on the terminals, especially in humid environments. If there are issues with signal integrity, first verify the connections and then consider recalibrating the cold – junction compensation sensor if necessary. In case of component failure, replace the SCXI – 1300 with a new one following the installation steps in reverse. Calibration of the cold – junction compensation sensor is recommended periodically, usually annually, to maintain accurate temperature compensation.
