Analog Input 4 +
Differential ±5 V
* All Analog Inputs can be configured as single-ended 0-5 V, 0-10 V, 0-20 V or differential ±5 V, ±10 V
independently.
Upon request only, please contact
** Must be connected to Ground when the Analog Input is set to Single-Ended Mode.
It is recommended to use a separate ground cable for each single-ended analog signal/cable and twist
or tie them together.
*** This is a 5 V supply that can provide up to 100 mA for external use.
The supply is protected against short to ground and keeps the current below 400mA in a continuous
short.
**** This is a 10 V supply that can provide up to 25 mA for external use.
The supply is protected against short to ground and keeps the current below 100mA in a continuous
short.

V
-10V
+10V The input voltage between
the positive and negative
input pins.
Any voltage out of this range causes
saturation to min/max ADC value
V
-10V 0V
+10V The common mode voltage. Any voltage out of this range causes
saturation and inaccuracy in the
measurements.
V
-15V
+15V The tolerable voltage
between the positive input
pin and GND.
Any voltage out of this range
damages the analog input’s circuitry.
V
-15V
+15V The tolerable voltage
between the negative input
pin and GND.
Any voltage out of this range
damages the analog input’s circuitry.
