MoTeC ADL EDL - Manual (Page 18)

16 Overview
Options
Note that the number of inputs that are available depends on which options
are enabled. See Appendix B: Options Summary for details.
Measurement Methods
These inputs use the same measurement methods as the Analog Voltage
Inputs.
Input Voltage Range
The measurable input voltage range is 0 to 15 Volts. This allows selection
from a wide range of sensors.
Specifications
For full specifications see Appendix D: Input Characteristics.
Wide Band Lambda Inputs
The two high accuracy, fully temperature compensated Wide Band Air Fuel
Ratio measurement inputs can be used if the Lambda Option is enabled.
These inputs connect directly to a MoTeC 4 wire Wide Band Lambda Sensor
and are accurate to 1.5% up to 1.2 Lambda under all load and temperature
conditions.
Note that this is the Bosch LSM sensor and not the 5 wire Bosch LSU.
Note that NTK Lambda sensors should be connected to an Analog Voltage
input via the appropriate amplifier.
Switch Inputs
The 4 switch inputs are generally used for the external switches required to
operate the ADL display. They can also be connected to a brake switch or
other switch.
These inputs have a 4700 ohm resistor connected internally from the input pin
to the 5V sensor supply so that a switch can be simply connected between
the input pin and 0 volts.
Options
All four inputs are available irrespective of which options are enabled.
