Input types

© Danfoss | April 2018
PLUS+1 ® modules have input or output pins that support multiple functions. Pins that support multiple
input or output types are user-configurable using PLUS+1
for the input/output (I/O) content of individual modules.
•
Digital (DIN)
•
Digital or Analog (DIN/AIN)
•
Analog or Temperature or Rheostat (AIN/Temp/Rheo)
•
Multifunction: Digital or Analog or Frequency (DIN/AIN/FreqIN)
•
Multifunction: Digital or Analog or Frequency or Rheostat (DIN/AIN/FreqIN/Rheo)
•
Fixed Range Analog or CAN shield (AIN/CAN shield)
Each PLUS+1 ® module input pin supports one of the above functional types. For pins with multiple
functions, input configurations are user programmable using PLUS+1

DIN

Digital inputs (DIN) connected to PLUS+1
input debounce is defined as an input being in a given state for three samples before a state change is
reported. The sample time is a function of application loop time.
Multifunction pins that are configured to be Digital input (DIN) are subject to the same update rates as
the Analog input (AIN) function for that pin. Debounce is not used, as hysteresis is built into the function.
The time to recognize a transition is dependent on the timing of the switch activation and the sample
rate.
