Description
The TBX-1303 Isothermal Terminal Block, with part number 777207-03, falls under the category of SCXI & Legacy equipment. This model is specifically designed for compatibility with a variety of SCXI modules, including the SCXI-1100, SCXI-1181, SCXI-1102, and SCXI-1102B/C. Its mounting is conveniently designed to be DIN rail-mountable, ensuring ease of installation in various setups.
Among its notable features are its automatically ground-referencing capability, the ability to detect open thermocouples, and an isothermal construction. This terminal block supports a total of 108 terminals, which includes Shield, CH+, and CH- for every input channel, facilitating robust and versatile connections.
When it comes to temperature sensing, the TBX-1303 offers both multiplexed and direct temperature sensor modes. It can operate within a temperature range of 0 to 55 °C, with a temperature sensor voltage output range of 1.91 to 0.58 V. The voltage output accuracy is ±0.65 °C within a temperature range of 15 to 35 °C, ensuring reliable and accurate readings.
The device’s open thermocouple detection is implemented through a pull-up resistor between +5 V and CH+, and a bias resistor between chassis ground and CH-. Despite being declared obsolete by National Instruments, the TBX-1303 remains available at Apex Waves, offering a valuable solution for specific legacy systems and applications.
