Analog rPM Feedback
A two wire connection supplies an analog (0-10 VDC) signal that is directly proportional to the MOTOR 1 RPM. The range is 0 –
2500 RPM and it will output a proportional 0 – 10 VDC signal. If a dual blower system is used, only the RPM of motor 1 can be
read.
Note:
The minimum speed of an ECM is approximately 250 RPM. Formula for outputs below (tolerance +/- 5%):
•
VDC output = (RPM /250)
•
Rpm = (VDC * 250)
Output signal: 0 – 10 VDC @ 20 k ohm minimum input impedance and is short circuit protected (output impedance is 511 ohm to
protect against incorrect wiring).
•
Black Wire – Analog RPM output com (-)
•
White Wire – Analog RPM output signal (+)
