No. Signal Description
A Encoder A Single channel, pulse train or quadrature A input.A- Encoder A (NOT)
B Encoder B Quadrature B input.
B- Encoder B (NOT)
Cm Power Return Internal power source 250 mA (isolated).+V 5...12V Power(1)
(1) If Encoder requires 24V power, it must be supplied by an external power source.
Output DIP switch selects 12 or 5 volt power supplied at terminals “+V” and “Cm” for the encoder.
