Description
The National Instruments TBX-1303 Isothermal Terminal Block, with part number 777207-03, is a versatile 32-channel Terminal Block compatible with a range of SCXI modules, including SCXI-1100, SCXI-1181, SCXI-1102, and SCXI-1102B/C. Designed for easy installation, this terminal block is DIN rail-mountable and features special isothermal construction with automatically ground-referencing and open-thermocouple loop detection, ensuring accurate and reliable temperature measurements.
Constructed with special plastic reinforced packing material, it minimizes thermal gradients and offers a high-impedance path to ground when used with the SCXI-1102 and SCXI-1102B/C. Users can also configure the channels on the SCXI-1100 to be either floating or ground referenced in segments of eight channels.
Equipped with 108 terminals, including Shield, CH+, and CH- for each input channel, the TBX-1303 also provides a built-in thermistor temperature sensor for effective cold-junction compensation, which is essential when using thermocouples with SCXI modules. Capable of operating in both multiplexed temperature sensor mode and direct temperature sensor mode, it accommodates various application needs.
Lastly, the TBX-1303 is designed to perform within an operational temperature range of 0 to 55 °C, ensuring stable performance across various environmental conditions.
