 There are six digital output circuits in total, which use the open-collector output structure as
shown in the figure. They can be used to drive the relay coil or optical coupler load. The loading
capacity is shown in the figure.
 If an inductive load such as the relay coil is connected, a free-wheeling diode must be connected,
as shown in the figure. If an optical coupler is connected, a current limit resistor must be
connected; otherwise, the drive may be damaged.

 Phases A, B, and Z of the encoder provide differential output signals. You are recommended to
use AM26C32 or equivalent chip and connect an end-matching resistor of about 220Ω.
 No isolation is made for any output circuit.
