- Page 10 NI 9215E Circuitry The NI 9215E channels share a common ground that is isolated from other modules in the system. The NI 9215E protects each channel from overvoltages. For more information about overvoltage protection, refer to the Specifications section. The incoming analog signal on each channel is buffered and conditioned by the instrumentation amplifier and is then sampled by a 16-bit ADC.
