Contact Protection Circuit for Relay Output
Depending on the load, a protection circuit may be needed for the relay output of the OpenNet Controller. Choose a protec-
tion circuit from A through D shown below according to the power supply and connect the protection circuit to the outside
of the relay output module.

Varistor
Protection circuit A can be used when the load impedance is
smaller than the RC impedance in an AC load power circuit.
C: 0.1 to 1 µF
R: Resistor of about the same resistance value as the load
Protection circuit B can be used for both AC and DC load
power circuits.
C: 0.1 to 1 µF
R: Resistor of about the same resistance value as the load
Protection circuit D can be used for both AC and DC load
power circuits.
Protection Circuit A Protection Circuit B
Protection Circuit C Protection Circuit D
Protection circuit C can be used for DC load power circuits.
Use a diode with the following ratings.
Reverse withstand voltage: Power voltage of the load circuit × 10
Forward current: More than the load current
