Main Features
Adjustable switching level between 0V and 16V at
input
DPDT 5A relay
Configurable to switch on rising or falling voltage
Adjustable hysteresis
High input impedance – won’t load down sensors
|
Suggested Uses For the Voltage Switch
Intercooler water spray control (from air-flow
meter, throttle position sensor or oxygen sensor signals)
Anti-lag turbo wastegate control (operating a
wastegate disconnect solenoid triggered from the air-flow meter
signal)
Nitrous oxide switching (from throttle position
sensor signal)
Intercooler fan control (from air-flow meter
signal)
Dashboard monitoring LED (eg, oxygen sensor
output signal)
Switching in and out engine management and auto
transmission control modifications (from air-flow meter, throttle position
sensor or oxygen sensor signals)
Low battery voltage warning and/or
disconnect

In car applications, many engine sensors have variable voltage
outputs and these can be used for relay switching. For example, if your car has
an air-flow meter with a voltage output (most cars have), then you can use that
as an engine load signal to switch things on and off.
