Analogue Inputs
Thanks to the A / D converter, it is possible to convert voltages into digital values. The conversion process always requires a certain amount of time in which the input must remain constant. The unipolar voltage of analog inputs is 0-5 V. Bipolar voltage is 0-10 v +/-5V or +/-10V.
Analogue outputs
A D / A converter has the analog outputs to convert a digital value into an analog signal. Depending on the type, D/A converters can generate voltages or currents of digital values. The voltage range can be chosen by software between 0-5 V & + / -5 V, or 0-10 V or + / -10 V. D / A converter with current outputs can deliver current supply 0-20 m A, 4-20 m A or 0-24 m A.
