Description
The part number 777687-28 is designed to be compatible with a range of modules, including the SCXI-1120, SCXI-1120D, SCXI-1121, SCXI-1125, and SCXI-1126. This component features 18 screw terminals, which includes a pair dedicated for chassis ground, accommodating a maximum field wire gauge of 26 to 14 AWG.
When it comes to accuracy, this part ensures a precise measurement with an accuracy of 0.5 °C within the temperature range of 15 to 35 °C, and 0.9 °C for the ranges of 0 to 15 °C and 35 to 55 °C. It utilizes DC coupling for its operations. Among its notable features are a high-precision thermistor, an aluminum isothermal plate, and an onboard temperature sensor, enhancing its functionality and reliability.
The maximum working voltage for this part is specified at 300 Vrms, applicable both channel-to-ground and channel-to-channel, ensuring safe operation within a wide range of electrical environments. It has a lightweight design, weighing only 7 oz, and its dimensions are 7.0 x 3.125 x 1.2 inches, making it compact and manageable for various applications.
It is built to operate efficiently within a temperature range of 0 to 50 °C and can be stored safely in temperatures ranging from –20 to 70 °C. Its humidity range is specified from 5 to 90% RH, noncondensing, allowing it to perform reliably under a wide range of environmental conditions. The part’s obsolete status has been announced, however, calibration services are still available through Apex Waves, ensuring its continued utility and performance accuracy.
