Frequently Asked Questions
Question 26: WHAT IS ANTI-STATIC PROTECTION CIRCUITRY? IS IT A LIGHTNING ARRESTOR?
Answer: 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-485/RS-422 transceivers against ESD levels. Static Protection Circuit is NOT a Surge Suppressor. 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, opto-isolated converter or isolator is recommended.
