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 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.
