Description
The TBX-1303 is an isothermal terminal block designed to enhance the functionality and performance of SCXI systems. With a part number of 183287A-01 (777207-03), it falls under the SCXI & Legacy category, indicating its compatibility and optimized performance with legacy systems. This model is specifically engineered to provide a seamless and efficient interface for SCXI modules such as SCXI-1100, SCXI-1181, SCXI-1102, and SCXI-1102B/C when used with thermocouples.
One of the key features of the TBX-1303 is its isothermal construction, which is critical for maintaining temperature uniformity across the terminal block. This feature, coupled with its capability for automatically ground-referencing and open-thermocouple loop detection, ensures high accuracy and reliability in temperature measurement and signal processing tasks. The terminal block is designed for easy installation, being DIN rail-mountable, which allows for a streamlined setup process in various industrial environments.
The TBX-1303 is constructed from special plastic reinforced packing material, providing durability and resistance to environmental factors. It includes 108 terminals (shield, CH+, CH- for each input channel), ensuring ample connectivity options for comprehensive system configurations. Moreover, it incorporates a thermistor temperature sensor for cold-junction compensation, enhancing the accuracy of temperature measurements by adjusting for the temperature difference at the junction.
Operating modes of the TBX-1303 include both multiplexed temperature sensor mode and direct temperature sensor mode, offering flexibility in addressing specific application requirements. The temperature sensor voltage range is specified as 1.91 to 0.58 V (0 to 55 °C), with a voltage output accuracy of ±0.65 °C (15 to 35 °C). This precision underscores the terminal block’s capability to deliver reliable data for critical applications.
Furthermore, the TBX-1303’s design incorporates open thermocouple detection, a feature
