Volts:
Measured on pin 35 of the EDC Top Connector.
Input Resistance: 83.8K Ohms
Range: 0 to 40 volts.
Sensitivity: 6400 counts per volt.
Note: A VI-221 or FM-VA-MVP-xx may be used to measure Voltage on any temperature channel.
Amps:
Common Mode Input Resistance: > 10 M Ohms
Di. Input Resistance: 10K Ohms
Dierential Input: + 2.5V to -.2V
Common Mode: +/- 90 Volt to ground
Sensitivity: 9.537uV per count.
Note: An FM-VA-MVP-xx module may be used to measure Voltage and Amps on any two temp
channels.
Fuel Flow:
Input Conguration: 5.11K Ohm pull-up to +5 Volts
Input Trigger: 2.5 Volt with over voltage protection.
Operating Range: 0 to 8.3 KHz.
Sensitivity: One count per pulse measure over a 0.356 second period.
Notes:
* +10 Volts are provided from the EDC to energize the ow transducer.
* An FFDM-1-MVP module may be used to accommodate fuel return from
a pressure carburetor.
* A FM-Flow-P module may be used to measure ow from a pulsed injector.
RPM, Piston (EDC-33P):
Two RPM channels are available. May be congured for digital or mag pickup. Also, may be set up to
operate from one or two inputs. Selectable jumpers and dierent EDC models accommodate 2, 4, 6, 8,
etc. cylinder engines. Inputs are over voltage protected. Mag Out feature provided.
Input Trigger: +3V / -1V
Input Resistance: 2.06K with 1 volt pull up.
Max RPM (EDC-33P-4/6): 4500, see Appendix for information on high RPM EDC units.
Sensitivity (EDC-33P-4/6): 20 counts per RPM
Note: A 79K isolation resistor (supplied in the kit) must be put in series with the input when measuring
signal from mags.
