Description
The 777207-03 is a model TBX-1303 terminal block categorized under SCXI & Legacy. This terminal block is designed for isothermal applications, supporting 32 channels. It is compatible with several units, including the SCXI-1100, SCXI-1181, SCXI-1102, and SCXI-1102B/C. The TBX-1303 can be easily mounted on a DIN rail, providing a convenient installation option.
Featuring an isothermal construction, the TBX-1303 includes 108 terminals (Shield, CH+, CH- for each channel), ensuring versatile connection possibilities. It incorporates advanced features such as automatically ground-referencing and open-thermocouple detection. The detection utilizes a pull-up resistor between +5 V and CH+ and a bias resistor between chassis ground and CH-, enhancing the accuracy and reliability of temperature measurements.
For accurate temperature monitoring, the TBX-1303 employs a thermistor temperature sensor that provides cold-junction compensation. The temperature sensor mode can be set to either multiplexed or direct, according to the requirements of the application. This terminal block operates within a temperature range of 0 to 55 °C and offers a sensor voltage output range of 1.91 to 0.58 V. The maximum voltage output accuracy is ±0.65 °C between 15 to 35 °C, ensuring precise temperature measurements across its operating range.
