8A High Current Outputs (8A HCO)
The Nexus PD16 features 10 high side outputs
capable of driving 8A to 12V. Each output has a
software programmable fuse current.
Once the electronic fuse blows the output turns
off for a software programmable delay duration,
before reactivating the output.
Use the NSP software to define the maximum
number of retries before the output is deactivated
until the next power cycle. The PD16 LEDs display
the output state.
8A HCOs are PWM capable and can be used
to power CAN devices or solenoids as well as
transmission shift solenoids, water pumps, etc.
Specs:
• Automatic overcurrent protection
• Flyback protected
• 0 to 30V voltage feedback
• High side current feedback
• 100Hz max switching speed
• Capable of 0-100% duty cycle
25A High Current Outputs
The four high/low outputs on the Nexus PD16
are capable of sinking 25A to ground and driving
25A to 12V. Each output has a programmable fuse
current, slow-start current and duration.
Once the electronic fuse blows the output turns
off for a pre-programmed delay duration before
reactivating the output. The PD16 LEDs display the
output state.
25A HCOs are PWM capable and can be used for
ignition power and injector power as well as to
PWM thermofans and fuel pumps etc.
Specs:
• Automatic overcurrent protection
• Flyback protected
• 0 to 30V voltage feedback
• High side current feedback
• 1kHz max switching speed
• Capable of 0-100% duty cycle

Analog Voltage Inputs (AVI)
Analog Voltage Inputs accept variable voltage
signals from 0V to +5V such as signals from
pressure, temperature and fuel level sensors.
These inputs can also accept switched inputs that
change between two different voltage levels.
The On Voltage and Off Voltage define what the
thresholds are between the on and off states.
The voltage can be viewed as a channel in NSP to
determine the thresholds for a switched input.
Common examples of switched inputs include A/C
Request switch and intercooler spray switch.
AVIs have a software selectable 1K pull-up
resistor to 5V, which can be enabled or disabled
within the Setup page.
Pull-up resistors are generally enabled for
temperature related sensors and switched to
ground inputs.
Specs:
• 0 to 5V
• 100 samples per second
• Selectable 1k pull-up to 5V
• -10 to 30V indefinite withstand
• 1.5kHz signal frequency max
• AVI-1 has a switchable 240Ω pull up
that allows
direct connection with fuel level sender input.

Pull-up resistors are generally enabled for
temperature related sensors and switched
to ground inputs. The following configuration
requires the pull-up resistor be enabled.
NOTE: AVI-1 has 1k or 240Ω pull up options for
fuel level sensors.

step-by-step set up guides, software
walk-throughs and tech tips go to


Sensors with a +5V supply do not require the pull-up
resistor be enabled, for example, rotary trim modules.
Any 5V pin can be used with any Signal Ground
pin for sensors.
