Analog Inputs
Analog Inputs 4
Input Voltage Range 0-5 V (default) or 1-5 V (software configurable)
Input Current Range
0-20 mA (default) or 4-20 mA (software configurable)
Note: external 250 ohm resistor must be installed for current inputs.
Please see wiring diagram for details.
A/D Converter Resolution 12 bit
Binary input range 0 to 32760
Update Rate 5 ms
Accuracy
+ 0.2% @ 25 °C (Voltage Input)
+ (0.2 + x) % @ 25 °C (Current Input) x=% accuracy of the external
resistor. Eg. Using 0.1% accuracy resistors (as supplied with the
LP-2/3): Accuracy = + 0.3% @ 25 °C
Isolation None
Input Impedance
10 kΩ
Debounce
Each analog channel is averaged over a configurable number of
samples. The current analog value is updated each I/O scan
