Input Types
The Syvecs X20L has 20 programmable inputs available and although they are fully configurable in
Scal, they are not all the same type of input which means sensors that for example require a pull up,
have to be assigned to different types….. Listed below are the 2 types which are available.
Flexible Input – AS Inputs
These Inputs are able to swing above and below the reference ground meaning they can see Positive
Voltage as well as Negative. Fully Adjusted trigger thresholds for frequency decoding is supported on
these pins and they can be used with a vast selection of other sensors from Digital, 0-5v, SENT,
Thermistor and MagnetoResistive
Example of sensors normally used on these Inputs are:
- Reluctor Crank and Cam Sensors / ABS Sensors for wheel speed
- Hall Sensors
- Map Sensor
- Temperature Sensor
- SENT Sensors
Bipolar inputs are not just limited to the above they can also be used for any sensor that outputs 0-
5volts. They are also able to provide a 3k Pull-up through Scal when the Input Type is set as
Thermistor
