National Instruments 777966-20 Strain/Bridge Input Module for SCXI.
The part number 777966-20 from National Instruments is the identifying part number for the SCXI-1520 Strain/Bridge Input Module for SCXI. This module supports multiple bridge configurations including quarter, half, and full-bridge setups, making it suitable for a wide range of sensor types. This module attributes to 8 analog input channels with an input coupling of DC and is equipped with voltage gain settings ranging from 1 to 1000 Volts. This module is also incorporated with overvoltage protection which includes ±35 V when powered on and ±25 V when powered off.
Its key feature includes excitation voltage setting between 0.0 to 10.0 V in 0.625 V increments as well as contains the short circuit protections with other protective features as well such as the surge arrestors in parallel with excitation terminals, shunt to ground. It has excellent calibration capabilities through two independent points with switching resistance of 32 Ω typ 50 Ω max, switch off leakage <1 nA and switch break-down voltage of +60 VDC.
The 777966-20 Strain/Bridge Input Module is equipped with 4-pole butter-worth low pass filter type that can be set to frequencies ranging from 10 Hz to 10 kHz or bypass together. When the filter is bypassed, it has a bandwidth of –3 dB at 20 kHz providing a wide frequency range for various application. Additionally, it has simultaneous sample and hold stages for synchronized data collection that results in interchannel skew of 200 ns typ and intermodule skew of 200 ns typ with a droop rate of 30 mV/s typ, 100 mV/s max.
This module has physical dimensions of 3.0 × 17.2 × 20.3 cm (1.2 × 6.9 × 8.0 in.) and weighs 750 g (1 lb 10.4 oz). Its operating temperature is 0 degrees Celsius to 55 degrees Celsius and a storage temperature of -20 degrees Celsius to 70 degrees Celsius with a relative humidity of 10% to 90% RH, noncondensing. It is required to mounted at an maximum altitude of 2000 meters and has a pollution degree of 2. It is compliant with IEC 61010-1, EN 61010-1, UL 61010-1, CSA 61010-1 standards making it suitable for measurement, control, and laboratory use.
