Description
The TBX-1303, with part number 183287B-01L (777207-03), falls under the SCXI & Legacy category. This device is compatible with a range of SCXI modules, including SCXI-1100, SCXI-1181, SCXI-1102, and SCXI-1102B/C. It’s designed for easy installation, being DIN rail-mountable, and can handle up to 32 channels.
The TBX-1303 is built with isothermal construction to maintain temperature uniformity across all channels. It boasts several key features such as automatically ground-referencing, the ability to detect open-thermocouple loops, and is designed with isothermal construction for improved performance. The terminal block comes equipped with 108 terminals, which include a Shield, CH+, and CH- for every input channel, ensuring comprehensive connectivity options.
For cold-junction compensation, the TBX-1303 utilizes a thermistor temperature sensor, enhancing its accuracy. It supports two operation modes: multiplexed temperature sensor mode and direct temperature sensor mode, providing flexibility in application. The device operates within a temperature range of 0 to 55 °C, with a temperature sensor voltage output ranging from 1.91 to 0.58 V across this temperature range. The voltage output accuracy is ±0.65 °C between 15 to 35 °C, ensuring reliable readings.
Despite being declared obsolete by National Instruments, the TBX-1303 remains available for purchase and repairs through Apex Waves, offering continued support for users of this legacy equipment.
