1. General

XPB Series Analog Input Isolated Barrier can cooperate with 2-wire transmitter, 3-wire transmitter and 2-wire current sources, provide isolated power supply for transmitter which located in hazardous area. The product transfers analog signal which generated by the transmitter from hazardous area to safe area separately. It restricts the energy from intrinsically safe port to hazardous  area, insuring the  system  against  explosion.  It  widely  used  in chemical industry, petroleum, natural gas, electricity, and other industrial fields. It is connected with all kinds of intrinsic safety instruments and used as the associated equipment of intrinsically safe explosion-proof system.
The  product  meets  GB3836.1-2010  Explosive  atmospheres - Part  1:  Equipment-General  requirements and GB3836.4-2010 Explosive atmospheres - Part 4: Equipment protection by intrinsic safety “i”. It has passed the test of China National Test Centre for Explosion Protect Electrical Products and obtained the Explosion-proof Certificate.
