RPM, Turboprop:

Two RPM channels are available to measure N1, N2, Ng, Nh, Hp, Hl or other turboprop RPM func-
tions. The “Engine Data, Ports, Timers, etc. Setup” screen provides data to calibrate these RPM values
for a given tach generator output.

EDC-33T (Both RPM Channels):

Input Trigger: +.39V / 0V (Hysteresis)
Input Resistance: 20K ohms
Max RPM: 125 Hz.
Sensitivity: 772.52 sensor counts per Hz.
Accuracy: <= .5%

EDC-33T-H1:

Ch 1, Rotor:

Input Trigger: +.39V / 0V (Hysteresis)
Input Resistance: 20K ohms
Max RPM: 260 Hz.
Sensitivity: 372 sensor counts per Hz.
Accuracy: <= .5%

Ch 2, N1

Input Trigger: +.11V / 0V (Hysteresis)
Input Resistance: 20K ohms
Max RPM: 6140 Hz.
Sensitivity: 16.1 sensor counts per Hz.
Accuracy: <= .5%

EDC-33T-W (Both RPM Channels):

Input Trigger: +.054V / 0V (Hysteresis)
Input Resistance: >1M ohm
Max RPM: 10.2K Hz.
Sensitivity: 8.963 sensor counts per Hz.
Accuracy: <= .5%

Pressure:

Input: 0 to 2.5 Volts Differential
Input Resistance: > 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 EI price sheet
for a list of pressure transducers available.
