The Static Protection Circuit is also called an ESD (Electro-Static Discharge). The charged capacitance of a human body enables a person to destroy integrated circuits with a single touch. Such a contact can easily occur during the installation of an interface cable. To prevent ESD damage, the converters come with the protection circuit to protect RS-422/RS-485 transceivers against ESD levels for up to 15kV. Static Protection Circuit is NOT a Lightning Arrestor. If the converters are to be connected to outdoor devices, to prevent your PC or other devices from being damaged by lightning strikes, proper lightning protection is required.
