Analog Inputs
The analog inputs are voltage inputs specified with an operating range of 0V to 10V DC. The
conversion resolution is up to 12 bit (0..4095). Please consult the RTCU IDE documentation for
further details.
The input signal is connected between AINx and AGND. AGND must be connected to the
reference of the connected equipment. Please be aware that deviations may occur, as the system is
very noise sensitive. Avoid long unshielded wires, and large fast-changing signals routed parallel
to the analog signals.
The inputs are low-pass filtered, ESD- and transient protected.
