Notes:

1.Total max. current 0.7A.

2.The inputs can be sine (sine and cosine) or square (phases A and B).

3.For single ended inputs use the ‘–’ input only.

The two non-connected wires per each encoder (Sine+ and Cosine+ should be floating, not grounded.

4.All the five GND pins (2, 20, 38, 12 and 30) are shortened. They appear five times to make the wiring easier.
