1
DC power supply

2
Emergency stop: Use an external switch
○
3
Fuse: Use 5 to 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 loads: Used for smaller loads.
2. Diode + Zener suppression of DC load: Used with larger loads, and for rapidly
switching applications.

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 ELCB internal program, to ensure safe operation in case of any unexpected
errors.
