Capacitive Fuel Level: The resistive and capacitive inputs share channels. Only one input type should be used
per channel.
Input Trigger Level: 2.1 Volts
Frequency Range: 0 to 15KHz.
Input Impedance: 33.2K Ohms
Sensitivity: 14 counts per Hz..
Notes: The Capacitive Fuel Level inputs may be used to monitor other functions.

Pressure:
Input: 0 to 2.5 Volts Differential
Input Impedance: > 20M Ohms
Common Mode Range on the Input: + 4 Volts to -.2 Volts (from ground).
+5 Volt and Ground provided to energize the pressure transducer.
Sensitivity: Ratiometric to the EDC +5 Volt supply (9.537uV x (5/(voltage of the EDC +5V supply)))
Notes: Many pressure transducers are available to monitor many different functions. See an E.I. price sheet for a
list of pressure transducers available.
