4.3 Analog inputs
The STD and DB15 models have two independent, unbalanced and multiplexed analog inputs which can
be configured in 0-50V mode. Please read section Interface Description 7 (DIP Switches) to learn how to
setup the mode of the analog input (current or voltage).
Both ADC inputs have a resolution of 10 bits, which means that the default resolution is 48.8mV (0-50V).
The A/D converter uses the successive approximation conversion technique.
The maximum A/D conversion rate is 5 samples per second.
To know how to read the analog inputs values please read the MTX-Java-IoT Family Software Manual.
4.4 Optoisolated I/O
The STD and DB15 models have two optoisolated inputs and two optoisolated outputs, located in the
DB15 HD expansion port. Please refer to section Interface Description 4.1 (Connector pinout) to view the
exact location of each I/O.
The electrical equivalent circuits of these I/O are shown in following figure:
