Description
The C Series Voltage and Current Input Module, manufactured by National Instruments, is identified by part numbers 781068-01, 785040-01, 781068-02, and 199272C-01L. This module is designed to accommodate a variety of applications with its 16 analog input channels.
It features a voltage input range of ±10.2 V and a current input range of ±21.5 mA, making it versatile for numerous measurement tasks. The voltage input impedance is greater than 1 GΩ, which is beneficial for minimizing loading effects on measured signals. Conversely, the current input impedance is approximately 85 Ω, suitable for current measurement applications.
The module boasts a maximum sample rate of 500 samples per second (S/s), ensuring timely data acquisition for dynamic signals. It also offers excellent noise rejection at 50/60 Hz, which is critical for maintaining signal integrity in electrically noisy environments.
Connection to the module can be made via a 37-pin DSUB or a 36-pin spring terminal, providing flexibility in wiring options. It accepts wire gauges ranging from 26 AWG to 16 AWG, accommodating various wire sizes for connection. The module’s weight is 5.1 oz when using the DSUB connection and 5.7 oz with the spring terminal, indicating its lightweight and compact design.
Furthermore, the module is built to operate in harsh environments, with an operating temperature range of -40 to 70 °C and a storage temperature range of -40 to 85 °C. This resilience ensures reliable performance even in extreme conditions, making it a robust choice for industrial applications.
