Danfoss PLUS+1 Series

pins are found below. Update rates for input expander modules are dependent on the CAN message
frequency selected in the application program.

Analog/Temperature/Rheostat (AIN/Temp/Rheo); Digital/Analog/Frequency/Rheostat (Din/AIN/
FreqIN/Rheo)
When a PLUS+1 module input pin is configured in the temperature/rheostat mode, the input has a 1.33
kΩ pull up resistor to +5 Vdc. It will source up to 3.75 mA current to an external load (RL) which then can
be measured. The equation for relating AD counts to a given load is: AD counts = (4096*RL) / (RL + 1330).
This calculation is solved internally and the ohms value is available for the programmer. The following
chart shows the relationship between AD counts and load resistance in ohms.
