Relay Output Module
Contains everything you need to control a 12v 40A relay (included) via the annunciator
function of the gauge. Kit includes necessary wiring, control module, and relay. Possible
applications are controlling an electric cooling fan, turning on/off a water/alcohol injection kit,
turning on/off a nitrous kit, etc. For example, one of our customers monitors knock retard and
when an unsafe level is seen the gauge turns off his nitrous system. OBD2 parameters as
well as analog inputs can be used to trigger the output. Firmware versions 2.6 (non CAN)
and 3.4 (CAN) have the necessary code to use this module. The version number can be
found on the back of each gauge. Prior versions will need to be reflashed. Contact
firstname.lastname@example.org for details if you have an older version.
NOTE: The speed and accuracy at which the relay activates is based on the vehicle's OBD2
bus. CAN bus vehicles will have the fastest response rates due to the increased speed of
these communication systems. Our PT, FD, and SR series gauges use a slightly slower
protocol but are still relatively fast (about 10x second), the ISO series may not be suitable for
applications that require very fast response times due the slower nature of these buses. The
user can determine if the response will be fast enough by watching the update rate of the
parameters being displayed. The output/annunciator will respond at the same rate as the
data shown on the display. Keep in mind that a data rate of "1" is the fastest. Refer to the
user manual for the procedure of setting the data rate.
One OBD2 connection splits into two gauge connectors allowing two single gauges to be
used as a dual. Single FD and single SR gauges are not meant to be run as duals however.
3 Wire Harness:
This is the analog input/power input harness that comes standard with every gauge
For those that have accidentally scratched the inside surface of the lens (the outer surface with the rounded edge is coated with scratch resistant and anti-glare coating).
Gauges come configured with a black face and two tone black bezel with polished silver lip as shown on the main order page, with an included additional white face. Additional optional hardware such as silver face, logo faces, or brushed aluminum bezel can be ordered here.
*These faces only work on the latest hardware. They will not work on the old style gauges with unremovable bezels.
