Appendix C: Input Characteristics
Analogue Voltage Inputs
Suitable for: Potentiometers, voltage output sensors and
Variable resistance sensors.
Measurement Voltage
Range: 0 to 15 V
Input Resistance: 100k ohms to 0 V
Resolution: 3.74 mV
Filter: 150Hz 1
st
order
Measurement Method: Absolute
• Note that variable resistance sensors require a pullup resistor to the 5V
sensor supply. (Normally a 1000 ohm resistor is used)
• Note that voltages outside the input voltage range may affect the readings
on other inputs.
Analogue Temp Inputs
Suitable for: 2 wire variable resistance sensors and some
voltage output sensors
Measurement Voltage
Range: 0 to 15 V
Input Resistance: 1000 ohms to the 5V sensor supply and 100k ohms
to 0V.
Resolution: 3.74 mV
Filter: 150Hz 1

order
Measurement Method: Absolute
• Note that some voltage output sensors may not be able to drive input
resistance.
• Note that voltages outside the input voltage range may affect the readings
on other inputs.
When used as Switch Inputs
The Analogue Temp Inputs may also be used as Switch Inputs
