AI terminal pinout
4 analog inputs and two temperature inputs are provided on the two 10-pin headers shown above.
Each analog input accepts 0~5V, 0~10V, -5~5V, -10~10V, 0-20mA, 4-20mA, or 4-24mA signals,
internally scaled and measured by an ADC connected to the SPI4 bus. Voltage inputs are connected
by supplying V+ and GND to the connector from the signal source. Current inputs are connected using
I+ and GND. Final values are computed based on software configuration.
An application to configure and use the analog inputs is provided by OnLogic and ships in
OnLogic-installed operating systems. Calibration updates can be made in the application by adjusting
the scaling factor applied as measurements are computed.
For details of use, see the FR200 software documentation.
Temperature inputs may be connected to 2-,3-, or 4-wire sensors. Excitation current is supplied
between TI+ and TI-, and the sensor input is measured between TV+ and TV-. To connect a 2- or 3-wire
sensor, short the appropriate missing wires at the connector (ex. for a 2-wire sensor, connect TI+ to
TV+, TI- to TV-, and then connect TV+ and TV- to the sensor).
Excitation current is configurable via software, and the temperature must be derived from the voltage
measurement based on the performance curve of the sensor connected.
