A/D – Refers to analog-to-digital conversion. The conversion produces a
digital value whose magnitude is proportional to the instantaneous
magnitude of an analog input signal.
Attenuation – The reduction in magnitude of a signal as it passes
through a system. The opposite of gain.
Channel – Refers to one of the sets of signal interfaces available on a
module’s terminal block.
Channel update time – For analog inputs, the time required for a
channel to sample and convert signals and make the resulting data
available to the processor. For analog outputs, the time required for the
