Using the Click 223
The Click 223 dual-485 surge protector device is designed to prevent electrical surges from damaging connected
equipment. It protects one DC power and two RS-485 serial connections from these incoming surges, which
are usually caused by lightning strikes and carried along underground cables. The Click 223 can be used with a
number of devices, including the SmartSensor Advance.
