There are different types of Signals pertaining to the JNIOR I/O and its expansion modules.
Digital Input signals represent the internal inputs on the JNIOR. The max channel number that can be monitored in Tasker is 16. The values that can be monitored of inputs is there states (if they are on or off).
Relay Output signals represent the internal outputs on the JNIOR. The max channel number that can be monitored in Tasker is 16. The values that can be monitored of inputs is there states (if they are on or off).
Temperature Probe signals represent values from the Temperature Probe. The max channel number that can be monitored is 2, as only two Temperature Probes can be connected at the same time. The values that can be monitored from the Probe is the degrees its reading in Celsius or Farhenheit.
Environmental Sensor signals represent values from the Environmental Sensor. The max channel number that can be monitored is 2, as only two Environmental Sensor can be connected at the same time. The values that can be monitored from the Sensor are Celsius, Farhenheit or Humidity.
4-20ma Input signals represent the inputs on the 4-20ma expansion module. The max channel number that can be monitored is 8, since each module has 4 inputs and you can have 2 connected max. The values that can be monitored from the 4-20ma inputs is the raw value, which monitors the input in units, and the scaled value which monitors the inputs in MA from 4 to 20.
4-20ma Output signals represent the outputs on the 4-20ma expansion module. The max channel number that can be monitored is 4, since each module has 2 outputs and you can have 2 connected max. The values that can be monitored from the 4-20ma outputs is the raw value, which monitors the input in units, and the scaled value which monitors the inputs in MA from 4 to 20.
10volt Input signals represent the inputs on the 10volt expansion module. The max channel number that can be monitored is 8, since each module has 4 inputs and you can have 2 connected max. The values that can be monitored from the 10volt inputs is the raw value, which monitors the input in units, and the scaled value which monitors the inputs in Volts from 0 to 10.
10volt output signals represent the outputs on the 10volt expansion module. The max channel number that can be monitored is 4, since each module has 2 outputs and you can have 2 connected max. The values that can be monitored from the 10volt outputs is the raw value, which monitors the output in units, and the scaled value which monitors the inputs in Volts from 0 to 10.
