34.4.26.24 Custom Temperature
The GEA 24 and GSU 73 MISC TEMP inputs allow the monitoring of installer-defined temperature
measurements, using the following sensor configurations:
•
Type J Thermocouple
•
Type K Thermocouple
•
MS28034 / MIL-T-7990 RTD
•
UMA 1BxR RTD (or any Pt100-type RTD)
•
Thermistor (any 50-150°C thermistor such as the Rotax 965531 or VDO 320-XXX series)
These inputs allow the display of arbitrary temperature measurements, and allow the installer to specify the
name of the gauge.
34.4.26.25 Custom Analog Measurements
The GEA 24 and GSU 73 general purpose (GP) inputs allow the monitoring of installer-defined analog
parameters, which may be used for a variety of purposes. Selecting “Custom Analog” for a GPS input
allows the installer to enter up to 8 points of voltage-to-numeric calibration, as well as specifying the name
of the gauge
The values displayed for Custom Analog gauges are “unitless”, which allows the GP inputs to display a
calibrated value for any compatible analog voltage measurement. This includes O2 sensors, timing
advance, additional bus voltage inputs, and other applications with compatible voltage levels. The installer
can. See pin description in
Section 25
for allowable input voltage range.
NOTE
The GEA 24 GP 6 and GP 7 inputs require the LO side of the input to be connected to
ground. See
for wiring details.
