Description
The 776573-21 is a terminal block designed for use with SCXI & Legacy equipment, specifically the SCXI-1321 model. This product is an Offset-Null and Shunt Calibration Terminal Block, which is compatible with the SCXI-1121 module revision C or later. It includes 18 screw terminals and features a front-panel trimming potentiometer for user adjustments.
Moreover, the SCXI-1321 offers shunt calibration circuits that are software controllable, enhancing its versatility in various applications. The shunt resistor is a 301 k Ohm (socketed), allowing for easy replacement or modification as needed. This terminal block can accommodate a maximum field wire gauge of 26-16 AWG, making it suitable for a wide range of wiring configurations.
In terms of performance, the terminal block provides a cold junction sensor output and accuracy of ±10 mV/°C and 1.3 °C, respectively. It is designed to operate safely within a maximum working voltage of 300 V (CAT II). For optimal performance, it is recommended to use this terminal block within an operating temperature range of 0 to 50 °C, with a storage temperature range of –20 to 70 °C. The relative humidity range for operation is 10 to 90% (non-condensing).
Compliance with multiple electrical safety standards, including IEC 61010-1, EN 61010-1, UL 3111-1, UL61010B-1, and CAN/CSA C22.2 No. 1010.1, ensures that the SCXI-1321 meets rigorous safety and reliability criteria. Although its obsolete status has been announced, calibration services for this terminal block are still available. It is recommended to undergo calibration <
