National Instruments 785188-01 Voltage Input Module
As a member of the NI-9220 series, the National Instruments 785188-01 is a C Series Voltage Input Module. This module enables simultaneous differential analog inputs with 250 Vrms CAT II or 60 VDC CAT I isolation. With its 16-bit resolution, it offers 16 channels for accurate measurements within ±10 V.
This module guarantees smooth platform interoperability and seamless integration when used with CompactDAQ and CompactRIO systems. Because of its sturdy construction and small size, it may be used in a variety of industrial settings and provides flexibility and dependability for data collection jobs.
The 785188-01 facilitates installation and setup ease of use by offering two connector alternatives: a 37-position D-SUB connector and a 36-position spring-terminal connector. These options allow the device to meet various connectivity demands. With a maximum voltage tolerance of ±10.4 V of common mode, each channel of the 785188-01 gives a measuring voltage range of ±10.4 V to ±10.6 V. With its overvoltage protection up to ±30 V, the module guarantees the security of linked systems as well as the device itself.
This module can produce 3.2 MB/s of data throughput while operating at a maximum sampling rate of 100 kS/s, which makes high-speed data acquisition tasks easier. Because of its stability features, which include offset drift of 29 μV/°C and gain drift of 5 ppm/°C, measurements are consistently precise and dependable even under changing environmental conditions.
Impressive specifications of the 785188-01 include a CMRR of 70 dB, a -3 dB bandwidth of more than 100 kHz, an input impedance of more than 1 GΩ, and low input noise of 0.85 LSBrms. It also has outstanding -90 dB crosstalk performance and settling periods of 19 μs for a 10 V step and 26 μs for a 20 V step.
