The output of the transistor is
“open collector”.
1.
Diode suppression: Used for smaller loads.
2.
Diode + Zener suppression: Used for larger loads and for rapidly switching
application.

Mutually exclusive output: For example, Y3 and Y4 control the forward running
and reverse running of the motor, forming an interlock for the external circuit,
together with the ELCM internal program, to ensure safe protection in case of
any unexpected errors.
