Emergency stop: Uses external switch
○
3
Fuse: Uses 5~10A fuse at the shared terminal of output contacts to protect the output circuit
○
4
Transient voltage suppressor (SB360 3A 60V): To extend the life span of contact.
1. Diode suppression of DC load: Used when in smaller power [Figure 1]
2. Diode + Zener suppression of DC load: Used when in larger power and frequent On/Off
[Figure 2]

Manually 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 PLC
internal program, to ensure safe protection in case of any unexpected errors.

The output of the transistor model is “open collector”. If Y0/Y1 is set to pulse output, the
output current has to be bigger than 0.1A to ensure normal operation of the model.
