2.6 Analog Sensors
2.6.1 Voltage Sensors
Environmental measurements can be determined by reading a simple voltage output from a
sensor. The voltage level is proportional to the measurement parameter. Every NexSens iSIC
ships standard with (8) analog channels. (8) additional analog channels can be added with a
factory installed analog expansion. The iSIC can measure voltages up to 2.5V (ie 0-1V, 0-2.5V,
0-custom voltage). If the sensor outputs a higher voltage two resistors are required to measure
the sensor reading. Contact a NexSens application engineer for more information regarding your
specific sensor.
Single-Ended (Non-Isolated) Voltage Sensors
Connect single-ended analog mV input devices to the analog terminal strip. A diagram of this is
shown below:
Pins AD0 through AD7 can all be used for connecting single-ended analog mV sensors. Eight
sensors can be connected at the same time using these pins on the analog terminal strip.
