RS232-25 Pin interface lightning arresterDetailed product description：

Function and application scope:
RS232 interface lightning arrester, with two types of 25 core or 9-core D-type standard connectors, can provide precise overvoltage protection for communication lines defined by standard or non-standard standards. Advanced American standard integrated overvoltage protection devices not only achieve efficient and reliable anti high voltage pulse impact function, but also make the lightning arrester look beautiful and elegant.
This series of products is particularly suitable for computer systems in industries such as government agencies, finance, securities, and insurance as fine protection for corresponding interfaces, and can be used as anti surge protection devices for printer interfaces, effectively reducing software and hardware failures caused by pulse interference on equipment.

Usage:
Simply string the 25 core, 15 core, or 9-core D-type standard connector RS232 interface lightning arrester into the data cable. The XB-COM-D9 RS232 interface lightning arrester needs to be grounded.
Function and application scope:
Suitable for rotary table and rotary cup electrostatic spraying, handheld and fixed electrostatic powder spraying, electrostatic scale removal, electrostatic flocking and other electrostatic new processes.

Technical Specifications:

model	XB-SL-DATA
Nominal current capacity (8/20 μ s)	5KA
clamping voltage	24V
Insertion wear and tear	<0.5dB
response time	<1ns
Insert resistor	<2 Ω
interface method	terminal block

Installation and maintenance methods:
At the front end of the protected equipment's line, connect the XB-SL-DATA data dedicated line lightning arrester in series, with the input terminal (2-3) IN connected to the data transmission line and the output terminal (2-3) OUT connected to the protected equipment, and make a reliable electrical connection between the lightning arrester grounding terminal and the ground wire.
If it is found that the installed lightning arrester cannot transmit data normally, remove the lightning arrester and directly connect it to the equipment. If it still cannot transmit normally, the lightning arrester is intact and other reasons should be investigated.
