Output Configurations for PLUS+1® Controllers
PLUS+1 controllers have configurable outputs that can be used to drive a variety of different loads.
Danfoss recommends the following ways for using the PLUS+1 outputs to drive different types of
loads.
Danfoss recommends using a digital output for ON/OFF loads, such as a relay or valve. This
encompasses outputs labeled as DOUT or DOUT/PVG Pwr. The recirculating diode across the relay coil
is optional. The internal diode will provide the same functionality. These outputs always provide a
high voltage (sourcing battery voltage) as the output when in the ON state.

Ground
If you need to use a multi-function PWM output for ON/OFF loads, then set the configuration in
the application program to one of the digital output selections. This can be push/pull, sourcing, or
sinking. (PinConfig = 0, 1, or 2)
Sourcing and Sinking options are not available for all pins. Please refer to the API specification for the
particular hardware.
