About this file
This specification sheet details a 6-Axis Load Cell Amplifier Unit with comprehensive technical specifications. The device features 8 input channels with high-performance characteristics, including a 0.05% accuracy class, 24-bit resolution, and a sample rate of 48,000 synchronous samples per second. Key technical specifications include bridge input ranges of 2.0, 3.5, or 7.0 mV/V, bridge excitation voltage options of 8.75, 5, or 2.5 VDC, and configurable analog and digital inputs/outputs.
Environmental and power specifications indicate an operating temperature range of +32 to +122°F, a power supply of 12-28 VDC consuming less than 12 watts, and USB connectivity with various data packet configurations. The device connects via a 44-pin High Density D-Sub Connector and offers flexible output options, including ±10, ±5, 0-5, 0-10, 4-20, and 0-20 volt/milliamp ranges. This specification sheet aligns with the NASA/NSSC solicitation for a 6-Axis Load Cell Amplifier Unit, intended for use at NASA Armstrong Flight Research Center.
