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: 123 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: 266 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: 11.0K 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.
