SeaI/O Manual
88
On the SeaI/O-570 PCB, switch 5 (SW5) allows each of the eight A/D channels to be individually
configured for a thermistor by moving the corresponding channel selector (1-8) to the “ON”
position. This will apply a bias voltage of +5V through a 10K Ohm resistor. Connect the
thermistor between the input and ground reference on the SeaI/O-570‟s terminal block
connector. This will create a voltage divider and as the resistance of the thermistor changes so
will the voltage read by the application. Please reference the data sheet of the chosen
thermistor to calculate the measured temperature.
