What is the power consumption of the various sensor pins of the EMS?
I assume that EMS pins used to produce a OPEN/CLOSED contact annunciation icon on the Dynon screen itself are miniscule power consumers way down in the millivolt range...
My new plan based on the information received from my other post is to use PIN 15 as the power source for the following items:
-FLOSCAN 201B FUEL FLOW SENSOR RED WIRE
-WESTACK (WESTBERG MFG) FUEL CAPACITANCE PROBES (2 PROBES)
-FUEL COLLECTOR TANK LOW DISPLAY ON THE DYNON SCREEN (SIMPLE FLOAT SWITCH)
-DOOR OPEN ANNUNCIATION DISPLAY ON THE DYNON SCREEN (2 DOORS)
-HATCH DOOR OPEN DISPLAY ON THE DYNON SCREEN (MICROS-WITCH ON DOOR)
Would the pin 18 have sufficient capability for these items?
The only real current consumers on the list would be the Floscan fuel flow and the Fuel Capacitance Probes.
The fuel probes are Westberg 0-5 VDC probes and the manual dose not specify how much power the sending units draw (does someone have a manual they could share).
For the doors open indicators, I plan on using simple spring loaded micro-switches that have contacts that are open when compressed and closed when sprung outward and PIN 15 would provide the power to the "hot" side of the contact.
The fuel float is a simple switch that is open when the float is up and closed when the float drops and PIN 15 would provide the power to the "hot" side of the float switch.
The original plan was to use a 2 AMP CB to power my capacitance fuel probes and float switch however that would require having to turn the battery master on and leave it on for the simple task of checking the fuel quantity indications of the airplane...however...if I wire up the capacitance fuel probes to be powered by the Dynon itself then I could just power on the Dynon only and read the fuel quantity.
Thanks for your help!!!
