The 4.096V reference on pin 1 is current-limited by a 4.7K resistor. The Reference Adjust input is
limited by a 510K resistor and may have from 1V to 5V applied.
If the optional instrumentation amplifiers are present, the inverting inputs are connected to
ground through a 1M resistor. The non-inverting inputs are floating. Also, the instrumentation
amplifier outputs are available at the Input/Output pins.
If the amplifiers are not present, pins 6, 8, 14, 16, 22, 24, 30, and 32 are inputs.
If the board is configured to received 4-20mA inputs, simply connect your + wire to the Non-
inverting Differential input from your sensor, and the -wire to your power supply return.
