1. General

XPB Series RTD Input Isolated Barrier converts thermal resistance signal in hazardous area into a standard process signal that have a linear relationship with the temperature, and outputs to the safe area. It is intelligent, input type of RTD and temperature range can be configured through computer. 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.
