2.6 Isolated Output Inhibit
Provide input signal to inhibit output. Pin 11 is used as a signal to disable the module.
The inhibit pin is internally connected to the LED side of the optocoupler.
One requires an external 1kohm pull-up resistor.
The pull-up resistor is connected to the 5V power supply.
The maximum voltage of this pull-up resistor is 5V, and the maximum sink current is 5mA.
The default pin configuration is
• Op
tocoupler LED On = Output is Enabled.
• Optocoupler LED Off = Output is Disabled
