GE IS200TRLYH2C Axial displacement module

The encoder section uses differential type inputs to interface with up to five independent incremental encoders. These inputs accept RS422 level quadrature signals. A quadrature encoder sends square wave type signals. When the shaft rotates at a constant velocity, the A and B outputs are square waves and are at the same frequency. However they are out of phase with each other by 90°.

When the encoder shaft rotates in one direction

each A pulse leads the corresponding B pulse by 90°. When it rotates the other direction each A pulse lags its B pulse by 90°. The signals illustrated in Figure 21 indicate that the encoder shaft rotates in one direction at first. Its speed of rotation decreases to 0 and then it starts rotating the other direction. The signals are shown as differential. A is the inverse of the signal A and B is the inverse of signal B.
