Thiết bị cắt sét RS-422 FL422

• Features:
• Accord IEC61643-21、VDE0675、GB18802.1 standard
• Protected signal ground connection
• The high response surge arresters
• Inhibition voltage and low loss against high speed signal
• Easy to install, plug-and-play
• Installation instructions
• 1、The surge protector is connected in series and is installed as close as possible to the protected equipment.
• 2、When installing surge protectors, the device should be connected between the access line and the protected device.
• 3、Surge protector for fault detection when the product should be removed, measured between input and output resistance, should be less than 10Ω. Between the core wire and ground resistance should be greater than 10MΩ. If the measured data does not meet the above requirements, the product is faulty, should be replaced in time.
• 4、Lightning protection ground connection should be as short as possible, thick, straight.
• Typical application
• Overvoltage protection of the industrial equipment interface of RS485/RS422 protocol.
• Lightning protection for RS232-485 converter.
• Lightning protection and surge protection of industrial bus equipment using 5V level.
