Electronics International MVP-50T - Manual (Page 56)

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.
Temperature:
Input Range: 0 to 2.5 Volts Differential
Input Impedance: 12.1K Ohms on each input to ground
Sensitivity: 9.537uV per count.
Notes:
* Any Temp Channel may be used to measure any thermocouple probe or any device outputting a
voltage. In this way many different types of function may be monitored through a temperature channel.
See an E.I. price sheet for a list of modules available.
* A Reference junction is provided to accommodate TC probes. Temp channel 8 is closest to the “Ref
Diode” and is best used for measuring OAT.
Resistive Fuel Level:
The resistive and capacitive inputs share channels. Only one input type should be used per channel.
Input Range: 0 to 18 Volts single-ended input.
Input Impedance: 14.4K Ohms.
Sensitivity: .07169mV per count when set for non ratiometric measurement.
Notes:
* The Resistive Fuel Level inputs may be used to monitor other functions or annunciators.
* When monitoring a resistive probe a RFLM-4-12 or -24 module will be required (see E.I. price
sheets). Also, measurements are made ratiometric to the bus voltage.
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 6 KHz.
Input Impedance: 33.2K Ohms
Sensitivity: 14 counts per Hz..
Notes: The Capacitive Fuel Level inputs may be used to monitor other functions.
