National Instruments SCC-CI20 Current Input Module
The SCC-CI20 (Part Number: 777459-05) is a Current Input Module from National Instruments. This model has the capability to convert current into voltage. The NI SCC-CI20 Current Input Module utilizes a resistor and has the resistance value of 249 Ohms. The instrument inputs the output voltage to a DAQ as the voltage signal. The value for the signal voltage ranges from 0 to 5 volts. The DAQ device used is from the E series.
The National Instruments SCC-CI20 Current Input Module offers exceptional capabilities, such as the option to support two current sources simultaneously. The source can provide current up to 20 mA. This model also incorporates a differential instrumentation amplifier, which buffers the signal for every input separately. The instrument enables the user to complete measurements for scaling voltage. The in-house resistance of the device has a tolerance value of 0.05 %. The temperature coefficient of the resistance is 10 ppm per degree Celsius. The maximum power dissipated across the resistor is 0.25 watts. The maximum value for gain error is ± 0.1 %.
The National Instruments SCC-CI20 Current Input Module comes equipped with strong dynamic features. This model offers the dynamic bandwidth of 10 kHz. The instrument is compact, with the physical dimensions of 8.89 x 2.92 x 1.85 in centimeters. It comes with the built-in right-angle male connector with twenty pins, as well as one 4-pin screw terminal.

National Instruments SCC-CI20 Frequently Asked Questions
Question: How can I get the isolated equivalent to the SCC-CI20?
Answer: To achieve an isolated equivalent to the SCC-CI20, you could use one of the isolated analog input modules in conjunction with a precision resistor.
Question: How does the SCC CI20 convert current to voltage?
Answer: The SCC CI20 converts current to voltage by passing it through a precision 249 Ω resistor and sending the resulting voltage to the E Series DAQ device as a 0 to +5 V signal.
Question: How many current sources can the NI SCC-C120 accept?
Answer: The NI SCC-CI20 accepts up to two current sources at a maximum of 20 mA.
Question: Which device can the NI SCC-CI20 be plugged into?
Answer: The NI SCC-CI20 can be plugged into any analog input socket on the SC-2345.
