MoTeC Appendices 79
Appendix C: Input Characteristics
Analog Voltage Inputs
Suitable for: Potentiometers, Voltage output sensors & Variable resistance
sensors.
• Note that variable resistance sensors require a pullup resistor to the 5V
sensor supply. (Normally a 1000 ohm resistor is used)
Measurement Voltage Range: 0 to 15 V
• Note that voltages outside this range may affect the readings on other
inputs.
Input Resistance: 100k ohms to 0V
Resolution: 3.74 mV
Filter: 150Hz 1 st order
Measurement Method: Absolute
Analog Temp Inputs
Suitable for: 2 wire variable resistance sensors and some voltage output
sensors.
• Note that some voltage output sensors may not be able to drive input
resistance.
Measurement Voltage Range: 0 to 15 V
• Note that voltages outside this range may affect the readings on other
inputs.
Input Resistance: 1000 ohms to the 5V sensor supply and 100k ohms to 0V.
Resolution: 3.74 mV
Filter: 150Hz 1 st order
Measurement Method: Absolute
When used as Switch Inputs
The Analog Temp Inputs may also be used as Switch Inputs
Trigger Levels: Programmable 0 to 15V
Hysteresis: Individually programmable high and low levels.
