The NI CSM-10A Current Shunt Module delivers high-accuracy current measurement through precision shunt resistor technology. It measures the voltage drop across a 0.01 Ω shunt and converts this signal for direct readout by compatible data acquisition systems and digital multimeters. With ±0.5% accuracy from DC to 25 kHz, the module handles up to 10 A continuous current in demanding automotive, aerospace, and industrial environments.

– Compatibility & Integration
The CSM-10A connects directly to any data acquisition system or digital multimeter with standard 0.75-inch banana jack spacing. Confirmed compatible modules include the NI PXI-4070, NI PCMCIA-4050, and NI PXI/PCI-4060. Integration requires a computer system, compatible DMM, test probes (red and black), and a flat-head screwdriver.
