NI 9208 Spring,16-Ch current, +/-21.5mA, 24-bit,500 S/s AI module (785041-01)

500 S/s, ±20 mA, 16-Channel C Series Current Input Module
The NI‑9208 is designed with industrial systems in mind. It includes a high-resolution mode with 50/60 Hz rejection to remove low frequency noise. It has high-channel density to reduce the number of modules needed, which leaves slots open for other measurement types or for reducing the overall per channel cost of the system. The NI‑9208 uses a standard D‑SUB connection for use with cables and connector blocks.
