Relay (R) output circuit wiring
DC power supply
1
Emergency stop: Uses external switch
2
Fuse: Uses 5 ~ 10A fuse at the shared terminal of output contacts to protect the output
3
circuit
Transient voltage suppressor: To extend the life span of contact.
4
1. Diode suppression of DC load: Used when in smaller power (Figure 8)
2. Diode + Zener suppression of DC load: Used when in larger power and frequent On/Off
(Figure 9)
Incandescent light (resistive load)
5
AC power supply
6
Manually exclusive output: For example, Y4 and Y5 control the forward running and reverse
7
running of the motor, forming an interlock for the external circuit, together with the PLC
internal program, to ensure safe protection in case of any unexpected errors.
Neon indicator
