Relay (R) output circuit wiring
○
1
DC power supply
○
2
Emergency stop: Used an external switch
○
3
Fuse: Use 5 ~ 10A fuse at the shared terminal of output contacts to protect the
output circuit
○
4
Transient voltage suppressor: To extend the life span of relay contacts.
1.
Diode suppression of DC load: Used for smaller loads.
2.
Diode + Zener suppression of DC load: Used for larger loads and for rapidly
switching applications.
○
5
Incandescent light (resistive load)
○
6
AC power supply
○
7
Mutually exclusive output: For example, Y4 and Y5 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.
